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 — trim, compress, MP3 extraction, 9:16 reframing, watermark and more — is free with no account during the launch.
