- Convert it to .AVI in a few seconds.

What to expect
- AVI files are typically larger than the source MP4 - older codecs like Xvid compress less efficiently than H.264 or H.265.
- Re-encoding always causes a small quality loss; there is no lossless path from
MP4toAVI. - The AAC audio track is re-encoded to MP3 inside AVI, adding another lossy step; any embedded subtitles are dropped entirely.
Frequently asked questions
Will converting MP4 to AVI reduce quality?
Yes - re-encoding decodes and re-compresses the video, so some detail is lost. The loss is usually minor at high quality settings but cannot be avoided entirely.
Why is the AVI file bigger than my MP4?
AVI relies on older codecs (typically Xvid or MPEG-4 Part 2) that are less space-efficient than H.264 or H.265 used inside MP4, so the same content takes more storage.
Does HandBrake support AVI output?
HandBrake dropped official AVI output support in version 1.4.0 (2021); use
ffmpeg or the free converter above instead.Will my subtitles carry over to AVI?
No - AVI has no native subtitle track support, so any embedded subtitles in the MP4 will be lost.
