About compress video
Reduce video file size with adjustable quality. Keep high quality while saving storage space.
Compress Video runs on FFmpeg compiled to WebAssembly, so your video is processed on your own device instead of being uploaded to a server. The engine downloads once the first time you use a video tool and is cached after that. There is no queue, no watermark and no account.

How to compress video online
Add your video
Drag and drop an MP4, MOV or WebM file onto the tool or choose one from your device. The video engine loads the first time and is cached afterwards.
Set your options
Pick a quality level; the estimated output size updates as you change it.
Process the video
Click the action button and watch the progress bar — encoding runs locally, so speed depends on your device.
Download
Save the finished file. No upload, no watermark, no account.
Frequently asked
Is my video uploaded to a server?
No. Compress Video Online runs entirely in your browser using FFmpeg compiled to WebAssembly. Your video never leaves your device and we don’t store anything.
Which formats are supported?
MP4, MOV, WebM, AVI, MKV and most formats your browser can decode. Output is MP4, GIF, MP3 or PNG depending on the tool.
Is there a file size limit?
We don’t impose one. Processing time scales with length and resolution, and files over a few hundred MB can exceed a phone browser’s memory — compress or trim first if that happens.
Is Compress Video free? Do I need an account?
Yes, it is completely free and there is no account, sign-up or watermark. It is one of 78 free browser tools from ModelsGroup.
Does it work on my phone?
Yes, in recent versions of Safari and Chrome. Video encoding runs on the phone’s CPU, so long clips take longer than on a laptop.
