About AVI
AVI is an older container. Video is encoded with MPEG-4 Part 2 and audio as MP3 for broad compatibility with older players.
Private, in-browser processing
This tool uses FFmpeg, the open-source engine behind most professional video software, running inside your browser. The first time you use it, the engine (about 30 MB) is downloaded once and then cached, so later conversions start straight away.
Frequently asked questions
Are my files uploaded?
No. Processing happens on your device with FFmpeg compiled to WebAssembly, so your video and audio never leave your computer or phone.
Why does it take a while?
Video processing is demanding, and your browser does it on your own device instead of a big server. Short clips take seconds; long or 4K videos can take several minutes. Keep the tab open until it finishes.
Will the quality change?
The video is re-encoded at high quality, so differences are hard to see.
