Convert AVI to MP4
AVI is the format of older cameras, camcorders and software. The files are big and do not play on phones. FeatherCut turns them into light MP4s.

Tips
Good to know about AVI
- AVI often holds DivX, Xvid or MJPEG. These old codecs take a lot of space. H.264 gives similar quality in a much smaller file.
- FeatherCut never upscales. A 640×480 recording stays 640×480, it just takes less space.
- Got a whole collection of old videos? Convert them one by one, without uploading family recordings anywhere.

FAQ
Common questions
Will AVI play on my phone?
Usually not. After converting to MP4 it plays on any phone and can go to the cloud or YouTube.
Are private family videos safe?
Yes. The file is processed only on your computer and is never uploaded.
How much space will I save?
It depends on the file, but old AVIs converted to H.264 are often several times smaller.
