Compress video online: in your browser
A video too big to send usually means uploading it to a compressor that keeps a copy. Media Razor shrinks it locally with FFmpeg in your browser: small enough for email, chat or the web, with nothing leaving your device.
Drop your video into Media Razor.
Pick a resolution and quality preset (1080p, 720p, 480p…).
Download the smaller file: done.
FAQ
Are my files uploaded to a server?
No. Media Razor runs FFmpeg compiled to WebAssembly inside your browser: no byte of your file ever leaves your device, and there is no server.
How much smaller will my video get?
It depends on the source and the preset you pick: lower resolutions and quality presets (e.g. 480p) shrink the file the most, while keeping it perfectly watchable for chat and the web.
Is it really free?
Yes. Every tool is free with no account during the launch: trim, compress, MP3 extraction, 9:16 reframing, watermark and more.
