FFmpeg compiled to WebAssembly. The same engine that runs every video pipeline on the planet, running in your tab.
Privacy
Files never touch a server. The conversion engine downloads once (~30MB, cached for next time) and then everything happens in WebAssembly.
Limits
Browser memory caps practical file size around 500MB. For larger files, use a desktop tool like the original desktop version.
