How to compress a video

Add your video

Drop an MP4, WebM, MOV or MKV file. The first run loads the FFmpeg engine into your browser.

Pick your settings

Choose quality, resolution and frame rate. Lower resolution and frame rate shrink the file dramatically.

Wait and download

Watch the progress bar, preview the result, then download your smaller video.

Why use MediaForge Video Compressor

No upload, total privacy

FFmpeg compiled to WebAssembly runs inside your browser. Your videos never touch a server.

Pro-grade compression

The same encoder YouTube uses, tuned with quality, resolution and frame-rate controls for maximum savings.

Free and unlimited

No watermarks, no sign-up, no queue. Compress as many videos as you like.

Features that shrink files

Quality control

A single quality slider maps to FFmpeg's CRF scale, balancing visual fidelity against file size precisely.

Use case: finding the perfect size-to-quality ratio

Resolution scaling

Downscale to 1080p, 720p, 480p or 360p. Halving the resolution cuts the file size by up to 75%.

Use case: making 4K footage shareable

Frame-rate reduction

Drop 60 fps footage to 30 or 24 fps. Great for talking-head videos where smoothness matters less.

Use case: lectures, webinars, screen recordings

MP4 or WebM output

Export as MP4 (H.264, maximum compatibility) or WebM (VP9, even smaller for web use).

Use case: websites, messengers, video hosting

Video compression FAQ

Typical savings are 50-80%. The biggest wins come from lowering resolution and frame rate. A 4K 60 fps video downscaled to 1080p 30 fps can easily drop by 80% with barely visible quality loss.
FFmpeg is a full video engine. We compile it to WebAssembly so it can run in your browser, and that engine is cached after the first load. It is the price you pay for 100% private processing.
Videos under 200 MB and a few minutes long work best. Longer videos take more time and memory because processing happens in your browser. For very long files, consider splitting the clip first.
Keep the quality slider above 50 and differences are hard to notice on normal screens. Reduce resolution and frame rate first, then fine-tune quality. You can always re-run with higher quality.
Completely. Processing happens locally in your browser and your video is never uploaded anywhere. This is ideal for unreleased content, client work or personal footage.
