Convert 3GP to AVI
Updated Jul 2026
3GP is the compressed video format older mobile phones used to save space, and AVI is the older Windows video container that many media players and editing programs still expect. To convert 3GP to AVI, open the file in a converter and export it as AVI. Doing this on your own computer keeps the video off other people's servers.

How to convert 3GP to AVI

- Convert. The AVI file is written right next to the original, and nothing leaves your machine.
3GP vs AVI: what actually changes
| 3GP | AVI | |
|---|---|---|
| File size | Small, built for slow mobile networks | Much larger, since it doesn't recompress like 3GP |
| Quality | Lossy, compressed hard to save space | Lossless, keeps every frame at full quality from that point on |
| Compatibility | Plays on older phones and some mobile players, spotty elsewhere | Opens in most Windows media players and legacy editing software |
| Editing support | Rarely accepted by video editors | Widely accepted, a longtime standard for editing timelines |
| Era | Early 2000s mobile format | 1990s Windows video container |
When to convert, and when not to
Convert 3GP to AVI when you want to open an old phone video in a Windows media player or editing program that won't read 3GP, or when you're moving old mobile clips into a more widely supported container.
If the clip only needs to play on a phone or get shared quickly, leave it as 3GP, since it already does that job in a much smaller file.
Why not just use an online converter?
Old 3GP clips are often personal, pulled straight from a phone backup or an old memory card. Sending one through an online converter means that video sits on someone else's server, even if just briefly. Converting on your own computer means the clip never leaves your machine, whether it's from 2009 or last week.
Questions
Does converting 3GP to AVI improve the quality?
No. 3GP already compressed the video when it was recorded, so that quality loss is permanent. Converting to AVI just repackages what's there into a lossless container, it can't bring back detail that's already gone.
Will the AVI file be much bigger than the 3GP?
Yes, often many times bigger. AVI doesn't recompress the footage the way 3GP does, so the same clip takes up a lot more disk space once converted.
Can I convert a whole folder of old 3GP videos at once?
Yes. Morphjet lets you drag in a folder of clips and convert them all to AVI in one pass, which helps with old phone backups full of small videos.
Why would I need AVI instead of just keeping 3GP?
AVI is what many Windows media players and older video editing programs expect. If a program won't open your 3GP file, or you want to edit the clip, converting to AVI usually fixes it.
Can this be done without uploading the video anywhere?
Yes. A desktop app like Morphjet converts the file on your own computer, so it never travels over the internet. You can do it with your wifi off.
