What is AVI?

Audio Video Interleave (.avi). AVI is Microsoft's video container from 1992. Old camcorders, webcams and 2000s downloads use it, often with DivX, Xvid or MJPEG video inside. It has no proper support for modern codecs or subtitles, so most people convert AVI files to MP4.

Common use: Old camera footage and legacy video files

Output format

What is 3GP?

3GPP Multimedia (.3gp). 3GP is the video format defined for 3G mobile phones. Phones of the 2000s recorded small, low-resolution 3GP clips with H.263 or H.264 video and AMR or AAC sound, so many old phone videos are in this format.

Common use: Videos from older mobile phones

Questions about AVI to 3GP

Is converting AVI to 3GP free?
Yes, one file at a time: the converter on this page runs in your browser, files up to 200 MB, no sign-up. The Filoshi desktop app ($29 once, for Windows) converts many files at once and has no size limit.
Does converting AVI to 3GP lose quality?
Yes, a little. 3GP is a lossy format, so some detail is thrown away when the file is saved. Filoshi re-encodes the video at a high-quality setting, so the difference is usually hard to see. AVI is lossy too, so this is a second round of compression; convert from the original, not from earlier conversions.
Is my AVI file uploaded anywhere?
No. The converter on this page runs in your browser with FFmpeg compiled to WebAssembly; your AVI file is read and converted on your device and never sent to a server. The desktop app works the same way, offline.
Has AVI to 3GP been tested?
Yes. AVI to 3GP is one of the 1,841 conversions that passed Filoshi's automated test matrix on Windows 11.
Can I convert many AVI files at once?
Yes, in the desktop app. Drop as many AVI files as you like on the window, pick 3GP once for all of them, and each file shows its own progress. The new files appear next to the originals, which are never changed.
