Why muxTools?
Privacy first
Your files stay on your computer. WebAssembly brings the full power of FFmpeg directly to your browser — nothing is ever uploaded.
Instant processing
Skip the upload queue. Processing runs locally on your own hardware, so there are no network bottlenecks or file size limits.
Works everywhere
All you need is a modern browser. No installation, no account, and it keeps working even when your connection drops.
