Offline Video Resize and Compression Tool for Creators
Resize, compress, trim, and fix videos locally for GoPro, drones, and phones with privacy.
Modern cameras make stunning footage, but they also make huge files. A weekend trip shot on a GoPro HERO12 Black can explode into tens of gigabytes. A family birthday filmed on an iPhone 15 Pro looks incredible, but sending it to relatives can feel like wrestling a suitcase through a mailbox slot.
A drone clip from a DJI Mini 4 Pro or DJI Mavic 3 is gorgeous, yet sharing it quickly is not always simple. And if you shoot interviews on a Sony FX3, a Canon EOS R6 Mark II, or a Nikon Z8, the quality is a gift and a burden at the same time.
That is exactly where this Video Resize / Reduce Size tool shines. It is built for real life video problems: downscaling, compressing, trimming, rotating, flipping, fixing slightly tilted horizons, and stripping metadata, all while running entirely on your own machine. Nothing is uploaded. Your browser does the work. Your files stay yours.
This local-first approach is not just a privacy win. It is a workflow win.
You get immediate control over output size and format without waiting for an upload.
You can process sensitive clips confidently, like client walk-throughs, internal demos, or family videos.
You can batch a folder and let it crank through everything consistently.
You can keep costs at zero while still getting professional-grade output.
And because it is part of ReportMedic, it fits the same practical philosophy: fast, focused tools that solve annoying problems cleanly.
The core promise: local, private, and under your control
A lot of video services start by asking you to send your footage somewhere else. That creates three problems: time, trust, and limits. This tool flips the model.
Everything runs locally
When you load the video engine, your browser becomes the processing workstation. That means the speed scales with your machine. A Mac mini, a ThinkPad, or a desktop PC will feel like a dedicated export box. Even on a laptop, the flow is direct and predictable.
Nothing is uploaded
Whether the clip came from a Sony RX100 VII on vacation, a Fujifilm X-T5 street shoot, a Panasonic Lumix GH6 event, or a Blackmagic Pocket Cinema Camera 6K test reel, the footage stays local. For creators, that is peace of mind. For teams, it is also compliance-friendly.
Free stays free
You are not paying per minute, per export, or per gigabyte. That matters when you have a folder full of clips from an Insta360 X3, a DJI Osmo Action 4, and a Sony ZV-1 after a single weekend.
Two modes that match how people actually work
The tool is built around two realities: sometimes you need to fix one video right now, and sometimes you need to clean up an entire folder.
Single video mode: fast, focused, and previewable
Single mode is perfect when you have one file to fix and you want to see the result immediately. Think:
Convert a large MP4 from a Canon EOS R5 into a smaller shareable version.
Rotate a vertical clip shot sideways on a Samsung Galaxy S24 Ultra.
Trim a screen recording to only the useful section for a client tutorial.
Reduce bitrate and size for sending on WhatsApp or posting quickly.
Single mode also includes an on-page preview of the output, which is a huge deal. You can confirm the framing, the rotation, the trim, and the overall look before you download.
Folder batch mode: consistent results at scale
Batch mode is what you reach for when you have volume.
Maybe you dumped 200 clips from a GoPro HERO11 Black after a skiing trip. Maybe you have a folder of drone passes from an Autel EVO II. Maybe you filmed a conference on a Canon EOS C70 and also grabbed behind-the-scenes on a Google Pixel 8 Pro.
Batch mode lets you:
Drop multiple videos or browse a folder.
Choose an output folder, so everything lands exactly where you want.
Apply one clean set of settings across the batch for consistency.
Override settings per file when one clip needs different rotation, resolution, tilt, or trim.
Track progress and status so you always know what is happening.
And if your end goal is one continuous video, there is a built-in option to merge all outputs into a single file once conversion finishes.
Quick Presets that turn common problems into one click wins
The tool includes GoPro Quick Presets, but they are not only for GoPro. They are smart defaults for the most common sharing destinations. If you have ever wondered, what settings should I use, this is the answer.
Quick Share
This preset targets a balanced 1080p output that is easy to send, easy to store, and easy to play everywhere. It is ideal for:
Family clips from an iPhone 14 Pro, iPhone 15 Pro, or Pixel 8 Pro
Travel highlights from a Sony A7 IV
Quick client proof videos from a Nikon Z6 II
Behind-the-scenes from a Sony ZV-E10
You get smaller files without turning your footage into mush.
Reels and TikTok
Vertical content is a different world. This preset is tuned for 9:16 output, which fits the modern scroll.
If you shoot vertical on a DJI Pocket 3, a Sony ZV-1, or a phone, it simply matches the platform. If you shoot horizontal and want vertical output, the tool uses a smart scale and crop approach to get a clean vertical frame.
That is perfect for:
Fitness creators repurposing wide camera footage into vertical clips
Travel creators turning landscape drone shots into vertical teasers
Product demos that need to look native on social
YouTube 4K
YouTube workflows often need quality preservation more than aggressive shrinking. This preset is built to keep detail where it matters.
If you recorded long form content on a Sony A7S III, a Panasonic Lumix S5 II, or a Canon EOS R6 Mark II, this preset keeps your export looking crisp while still benefiting from smart compression. It is also great for high-quality uploads from a RED Komodo or ARRI Alexa Mini test footage when you want a smaller review copy.
Archive Small
Sometimes the goal is not posting. It is storage.
Archive Small is ideal when you want to keep memories, keep documentation, keep B-roll, but reduce the footprint. This is where you can take large folders from an action cam like a GoPro MAX or Insta360 ONE RS and turn them into an organized, space-friendly archive.
It is also a perfect pairing with VaultBook. You can process clips locally, strip metadata, and then store the final versions inside VaultBook for a private, offline knowledge and media library.
WhatsApp
Messaging apps have their own reality: smaller files win. This preset is tuned to be friendly for sending quickly, while still keeping the video watchable and clear.
If you have ever tried sending a 4K clip from a DJI Mavic 3 or a long family video from a phone, you already know why this preset exists.
Target resolution: the knob that solves most problems
Resolution choices in the tool cover the practical range that people actually need:
Keep original
4K
1080p
720p
480p
Vertical 9:16 for Reels and TikTok
Square 1:1 for Instagram
Custom width and height with an option to keep aspect ratio
When to keep original
Keeping original is ideal when you primarily want a smaller file without changing dimensions. For example:
A high bitrate 1080p vlog from a Sony ZV-1 that you want to shrink
A screen recording that is already the right size but too heavy
A talking head clip from a Canon EOS R5 that does not need resizing
When 4K matters
If your output destination benefits from 4K, or you want to preserve detail in landscapes, product shots, or educational content, keep it 4K. A DJI Mini 4 Pro wide shot of a coastline or a Nikon Z8 cityscape can hold up beautifully when you keep resolution high and focus on quality settings.
Why 1080p is the universal share format
1080p is the sweet spot for most human sharing. It looks great on phones, laptops, and TVs, and it compresses well. It is perfect for travel videos from a Fujifilm X-H2S, family memories from an iPhone, or action footage from a DJI Osmo Action 4.
Why 720p is still incredibly useful
If your priority is smaller size and faster sending, 720p is a workhorse. It is excellent for:
Group chats
Quick client updates
Internal progress videos
WhatsApp and similar platforms
480p for extreme size sensitivity
480p is not about showing off detail. It is about sending a clip when the connection is weak, the recipient device is old, or the goal is quick reference.
Think job site documentation, classroom examples, basic how-to clips, or proof-of-work recordings.
Vertical and square outputs that match social platforms
This is one of the most powerful parts of the tool because it solves a real creator pain.
Vertical 9:16 output helps your footage feel native on Reels and TikTok.
Square 1:1 output is useful for certain Instagram formats and grid-friendly posts.
If you shot on a Sony A6400 horizontally, you can still create social-friendly crops without opening a heavy editor. If you captured a product unboxing on an iPhone in wide format, you can quickly repurpose it into vertical or square.
Custom width and height for niche requirements
Custom resolution is where this tool becomes a quiet hero for teams.
Need a specific size for an LMS platform. Need a specific dimension for a website hero. Need a specific frame size for a client portal. Custom settings let you do it precisely, with the keep aspect ratio option preventing accidental distortion.
Speed settings: control time-to-finish versus file size
The Speed selector is a classic practical feature: it lets you pick how hard the engine should work to compress.
Ultra fast
Very fast
Faster
Fast
Medium
In real terms, this is your control for balancing speed and compression efficiency. For a huge batch of clips from a GoPro HERO12 Black, choosing Very fast is a sweet spot. For a high-value final archive pass on footage from a Canon EOS R5, you might choose Fast or Medium to squeeze more size savings.
The best part is that it is not complicated. You choose your priority and move on.
FPS controls: make motion match the destination
FPS is a big deal because it shapes both file size and feel. The tool supports:
Keep original
60 fps
30 fps
25 fps
24 fps
Keep original for authenticity
Keep original is perfect when you want the footage to look exactly like it was captured. Action cams like GoPro, Insta360, and DJI action cameras often shoot high frame rates for smoothness. If that smoothness is part of the vibe, keep it.
30 fps for everyday sharing
30 fps is often the right call for social, messaging, and general playback. It reduces file size and still looks natural for most content.
24 fps for cinematic feel
If you are working with talking head content, storytelling pieces, or cinematic B-roll from cameras like Sony FX3, Panasonic Lumix GH6, or Fujifilm X-T5, 24 fps can be the aesthetic match.
25 fps for specific regions and workflows
If your workflow is tuned to 25 fps, or you work in systems that expect it, it is available.
Audio controls: keep it clean, or remove it entirely
Audio is often overlooked, but it is a chunk of size and a chunk of privacy.
The tool gives you:
AAC audio bitrate choices (from lighter to richer)
A Strip audio option for silent exports
Why audio bitrate matters
If you are posting a vlog from a Sony ZV-1 or Canon PowerShot G7 X Mark III, audio clarity matters. Choosing a solid AAC bitrate keeps speech crisp and music clean.
If you are sharing a quick clip where audio is not important, reducing bitrate helps shrink file size.
Why Strip audio is powerful
There are many situations where audio is unnecessary or risky:
Workplace walk-throughs where background conversations should not be included
Drone clips where wind noise adds nothing
Gym videos where music creates copyright headaches
Tutorials where you plan to add voiceover later
Strip audio gives you a silent, lighter export instantly.
Codec choices: H.264 compatibility or H.265 efficiency
Codec is one of the most important decisions, and the tool keeps it refreshingly simple:
H.264 for broad compatibility
H.265 for smaller files with modern efficiency
H.264: the safest universal choice
If you are sending files to mixed devices, older TVs, older laptops, or clients who should not have to think about playback, H.264 is the default hero.
H.265: when you want maximum size reduction
H.265 is great when your audience or your own devices are modern and you want smaller files. It is especially valuable for:
Long recordings from a Sony A7S III
Drone flights from DJI Mavic 3
Large batches of action cam footage
Archive copies that should take less space
You get more compression efficiency while keeping detail.
Quality control with CRF: the dial that actually makes sense
CRF is where this tool feels surprisingly professional. Instead of vague quality labels, you get a clear quality control that maps to file size and visual results.
The CRF slider lets you tune quality with intent:
Lower CRF means higher quality and larger files
Higher CRF means smaller files and stronger compression
How to think about CRF in real life
If you are posting polished content, like a YouTube upload from a Canon EOS R5 or Sony FX3, stay on the higher-quality side.
If you are archiving or sharing casually, like travel clips from a Sony RX100 VII or GoPro highlights, a balanced CRF keeps files small without looking rough.
If your goal is maximum shrink for messaging, push CRF toward smaller output and pair it with 720p.
This single control can take you from huge, hard-to-send files to clean, shareable clips without guesswork.
Transform tools: rotation and flip for instant fixes
We have all been there. You film a clip and it plays sideways. Or you mount a camera upside down. Or you record a selfie and want to correct the orientation.
The tool includes rotation and flip options that are simple and effective:
None
Rotate 90 degrees clockwise
Rotate 90 degrees counterclockwise
Rotate 180 degrees
Flip horizontal
Flip vertical
Real scenarios where this saves your day
A GoPro helmet cam mounted slightly off and needing a quick fix
A vertical phone clip recorded in the wrong orientation
A mirror shot on a Sony ZV-1 that you want flipped for readability
A drone clip that came in rotated from a specific mount setup
Rotation and flip apply across batch mode too, which is huge when an entire folder has the same issue.
Horizon and tilt correction: small feature, massive impact
This tool includes a Horizon / tilt correction slider, designed for those moments when the camera was just a little off.
If you have ever mounted a GoPro on a chest harness, handlebars, a helmet, or a car dash, you know the horizon can drift by a few degrees. The result is subtle but annoying.
Tilt correction lets you rotate the frame slightly to straighten the view. It is perfect for:
Action footage from GoPro HERO12 Black
Mountain bike clips from DJI Osmo Action 4
Ski clips from Insta360 ONE RS
Driving footage from a dash mount
Handheld walking shots from a Sony RX100 VII
You can also combine this with the crop-based social presets when you want to trim the edges and keep the frame clean.
In batch mode, tilt can apply globally, and you can override per file when only one clip needs special handling.
Trim: cut the noise, keep the moment
Trimming is one of the most valuable time savers because it reduces file size and improves the viewer experience at the same time.
The Trim section allows:
Start time
End time
Automatic duration readout
You can enter times naturally, like 0:30 or 1:45, and the tool handles it cleanly.
Trim use cases that show up everywhere
Remove the first 12 seconds of fumbling before the action starts on a GoPro clip
Cut the last minute of a drone clip where you are just landing
Extract the best 20 seconds of a product demo for social
Tighten a tutorial so it starts exactly at the point of instruction
Create short highlights for sharing without opening an editor
And because trim can apply across batch mode, you can do consistent cuts when you filmed a series with the same timing pattern.
Strip GPS and metadata: privacy protection built in
One of the most underrated features is Strip GPS / metadata. Many videos carry extra information that you may not want to share:
Location data from action cameras and phones
Device metadata
Creation details that are irrelevant to the viewer
With one checkbox, you can remove metadata from the output. That is a powerful privacy layer, especially for:
Home videos you share publicly
Client walk-throughs
Drone shots near sensitive locations
Family content where you want privacy by default
This feature also pairs beautifully with VaultBook. You can process and sanitize files locally, then store them in a secure offline system for long-term peace of mind.
Before, After, Saved, and Ratio: instant feedback that keeps you confident
Compression tools are often stressful because you do not know what you are going to get until it is done.
This tool gives you clear feedback:
Before size
After size
Saved amount
Ratio
That feedback is more than just satisfying. It helps you learn your own preferences quickly.
If you compress a Sony A7S III interview clip and see the ratio is excellent, you know that setting is a keeper for future videos. If you process a DJI Mavic 3 drone clip and want slightly more detail, you can adjust CRF with confidence.
Preview output in the browser before downloading
Single mode includes an output preview. This is a practical superpower.
Instead of exporting, downloading, opening another player, and guessing if the result is correct, you can:
Confirm framing for vertical and square crops
Verify rotation and flip are correct
Check that the trim points are right
Make sure audio choices match your intent
When you like what you see, you download the MP4.
Batch workflow features that feel like a real production utility
Batch mode is where the tool becomes a true workhorse.
Choose output folder
Instead of scattered downloads, you can select an output folder and keep your workflow organized. This is perfect when you are processing folders like:
A full day of clips from a GoPro HERO11 Black
A behind-the-scenes shoot from a Canon EOS R6 Mark II
Drone folders from DJI Mini 4 Pro
Social clips from a phone shoot day
Progress tracking and status
Batch processing includes clear status and progress indicators. When you are converting dozens of files, you always know where you are in the run.
Per-file overrides with a simple settings dialog
This is a standout feature: most batch tools force one size fits all settings. Here, you can override a single file for:
Resolution
Rotation and flip
Tilt
Trim
That means if 39 clips are fine but one was filmed upside down on a mount, you can fix only that one without changing the rest.
Merge all outputs into one video
If your end goal is a single combined file, you can merge the converted outputs into one continuous video. This is perfect for:
Multi-part event coverage
A long drive montage compiled from several segments
A travel day stitched together for easy viewing
A training session recorded in chunks
It is also a clean way to create one archive copy from many smaller clips.
Use cases that show the tool at its best
Now let us make it concrete. Here is how the features map to real creator and real-world scenarios, across different types of cameras and workflows.
Action cameras: fast sharing without losing the vibe
Action cameras like GoPro HERO12 Black, GoPro MAX, DJI Osmo Action 4, and Insta360 X3 are designed to capture movement, energy, and chaos. The downside is file size and volume.
This tool is perfect for turning action camera footage into share-ready versions:
Quick Presets give you one click settings for common destinations.
1080p and 720p targets shrink files dramatically.
30 fps output is ideal for sharing while keeping motion smooth.
Tilt correction fixes slightly off-angle mounts.
Trim removes the boring setup moments.
Metadata stripping protects location privacy.
The result is a clean highlight workflow that stays completely local.
Mirrorless and DSLR creators: compress without losing detail
If you shoot on cameras like Sony A7 IV, Sony A7S III, Canon EOS R5, Canon EOS R6 Mark II, Nikon Z6 II, Nikon Z8, Fujifilm X-T5, or Fujifilm X-H2S, you often start with very high-quality files.
This tool lets you create smaller versions for sharing, review, or backup:
Keep original resolution when the frame size is already right.
Tune CRF to preserve detail for faces, text, and fine textures.
Use H.265 when you want smaller files with modern efficiency.
Keep audio clean with the AAC settings for voice-heavy content.
It is a great way to create review copies for clients, or lightweight versions for quick internal approvals.
Cinema cameras and serious projects: fast dailies and quick proofs
Projects shot on Blackmagic Pocket Cinema Camera 6K, RED Komodo, ARRI Alexa Mini, Canon EOS C70, or Sigma fp often need a simple step: generate smaller proofs.
Instead of building a full NLE export pipeline for every quick share, you can:
Drop the file in single mode
Choose a sensible preset or quality setting
Trim to only the relevant section
Output a clean MP4 for quick viewing
That means dailies, proofs, and review clips stay private and fast.
Drones: make aerial footage shareable in minutes
Drone footage from DJI Mini 4 Pro, DJI Mavic 3, Autel EVO II, or similar platforms can be heavy. Even short clips can be large, especially at 4K.
This tool makes drone sharing simple:
1080p export is often the perfect compromise for social and messaging.
CRF lets you preserve detail in landscapes while still reducing size.
Metadata stripping helps protect location privacy.
Trim cuts takeoff and landing sections, keeping only the cinematic pass.
You keep the wow factor, lose the bloat.
Smartphone creators: content-ready exports without extra apps
Phones like iPhone 15 Pro, iPhone 14 Pro, Samsung Galaxy S24 Ultra, and Google Pixel 8 Pro create excellent video, but sharing can still be painful.
This tool gives you:
Social-ready vertical and square outputs
Easy compression for messaging apps
Quick trimming for highlights
Audio stripping for silent social edits or privacy
Rotation fixes for orientation mistakes
It is the simplest path from camera roll to shareable file, with everything staying local.
Vlogs and talking head content: consistent results every time
If you vlog on Sony ZV-1, Sony ZV-E10, Canon PowerShot G7 X Mark III, or Panasonic Lumix GH6, consistency matters. You want similar size, similar quality, similar motion.
The tool supports that consistency:
Pick a preset and stick with it
Fine-tune CRF once and reuse
Standardize fps across a batch
Keep audio at a reliable AAC bitrate
You get repeatable output without rethinking settings every time.
Screen recordings, tutorials, and internal training
A lot of video is not cinematic. It is instructional.
Screen recordings can be massive, especially long ones, and they often include sensitive data. Local processing is perfect here.
Compress to a smaller MP4 for sharing with a team
Strip audio if the recording does not need it
Trim out dead time and mistakes
Keep resolution custom to match LMS requirements
Strip metadata for privacy hygiene
For teams using ReportMedic for practical utilities and VaultBook for secure offline knowledge storage, this is a clean end-to-end system: process locally, store privately, share intentionally.
Real estate walk-throughs and on-site documentation
Walk-throughs filmed on a phone or a compact camera can include personal items, addresses, and sensitive context. Local processing plus metadata stripping is exactly what you want.
Reduce file size for quick sending to stakeholders
Trim to keep only relevant rooms or sections
Strip metadata for privacy
Export in 1080p for clear viewing without huge file sizes
Event coverage and family memories
For birthdays, weddings, reunions, school performances, and travel, the value is emotional. You want your originals safe, but you also want easy-to-share versions.
This tool is ideal for creating share copies:
Keep your originals untouched
Generate smaller MP4 versions for family groups
Trim to highlight the best moments
Use presets like WhatsApp or Quick Share to remove guesswork
And because everything runs locally, sentimental footage stays private.
A simple mental model for getting perfect results
If you want a practical recipe that works almost every time, think in three steps.
Step 1: pick the destination
Messaging and quick sharing: 720p or the WhatsApp preset
Social vertical: Reels and TikTok preset
YouTube: YouTube 4K preset or keep original with quality tuned
Archive: Archive Small preset
Step 2: control size with CRF
Higher quality for final posts and important videos
More compression for casual shares and storage efficiency
Step 3: fix reality with transforms and trim
Rotate and flip for orientation
Tilt correction for mount drift
Trim to remove useless sections
Strip metadata for privacy
You get results that feel intentional, not random.
Why this is powerful inside the ReportMedic and VaultBook ecosystem
On its own, this tool solves a big creator pain. Inside your broader workflow, it becomes even more valuable.
ReportMedic gives you a toolbox mindset: pick the exact tool you need, solve the problem, move on.
VaultBook gives you a secure place to store final versions, project notes, and even a structured archive of your media.
A simple example: you shoot a trip on a GoPro and a phone. You process a shareable batch locally, strip metadata, and store both the final highlight clips and the trip notes in VaultBook. That is a private, offline, organized memory system that does not rely on uploads or third-party storage.
Closing: a creator-friendly utility that respects your files
Video creation is supposed to be fun. The file management part is what ruins the mood. This tool exists to remove that friction: resize, compress, trim, rotate, flip, straighten, sanitize metadata, preview, batch, and export, all locally, privately, and free.
Whether you are cutting clips from a GoPro HERO12 Black, polishing drone passes from a DJI Mini 4 Pro, shrinking a Canon EOS R5 export for a client, or making phone videos shareable from an iPhone 15 Pro or Samsung Galaxy S24 Ultra, the workflow stays the same: drop the file, choose your goal, and let your machine do the work.
