The AVI file is saved to your downloads folder automatically once the job finishes.
AVI is one of the oldest video containers still in everyday use, and plenty of software from the Windows XP era onward expects it. Legacy editing suites, older presentation tools, certain DVD-authoring programs, and some industrial or lab equipment will only open AVI files, even in 2026. This converter turns modern formats like MP4, MOV, MKV, and WebM into AVI right in your browser.
A practical example: you recorded a clip on your phone as MP4, but the editing program installed on an older office PC refuses anything except AVI. Rather than hunting for desktop conversion software, drop the file here, wait for the progress bar, and feed the AVI straight into the old application.
100% private“Everything here happens on your own machine. The AVI is produced by FFmpeg compiled to WebAssembly running in your browser, so no copy of your footage ever touches a remote server.”
Mostly for compatibility with older software and hardware. Many legacy Windows applications, older media boxes, and some specialized equipment only accept AVI input, so converting is often the simplest way to keep those tools working.
It can be. AVI is an older container that predates modern high-efficiency codecs, so the same footage may take up more space than an equivalent MP4 or WebM. If size matters, you can tick the compress option in the dialog.
The tool accepts common formats including MP4, MOV, MKV, FLV, MPEG, MPG, OGG, WebM, and WMV, plus many others. If your file plays in a typical media player, it will most likely convert.
