AVI to 3GP converter
This makes a 3GP out of the AVI you already have. 3GP is the small, low-resolution video that old mobile phones recorded and sent by message. Your file never leaves your computer.

How to convert AVI to 3GP
- 1 Drop your AVI .avi file onto the page, or click to browse for it.
- 2 Set the quality, or leave the default, which keeps the file small without anything showing.
- 3 Convert. The work happens on your own machine, so how long it takes depends on your computer and the file.
- 4 Download the 3GP, or add more files and do the whole set in one go.
Why convert AVI to 3GP
- Very small files suited to constrained networks.
- Structurally MP4, so conversion is straightforward.
- Dashcam and cheap embedded camera output.
- AVI: poor support for modern video, subtitles and variable frame rates.
AVI compared with 3GP
How the two formats differ on the things that decide whether a conversion is worth making.
| Property | AVI | 3GP |
|---|---|---|
| File extension | .avi | .3gp |
| Compression | Lossy or lossless | Lossy |
| Typical file size | Depends on mode | Smaller |
| Introduced | 1992 | 2001 |
| Developed by | Microsoft | 3GPP |
| Standard | Proprietary | Open |
Quality and what changes
3GP stores the same content under a different set of rules, so what matters here is compatibility rather than picture quality. Convert once from the best source you have rather than through a chain of intermediate files.
- One 3GP limitation to keep in mind: low resolution and heavily compressed by design.
Questions about AVI to 3GP
Can I open a 3GP in a browser?
No. No mainstream browser renders 3GP natively, so it will download rather than display. That is fine when the file is heading into desktop software or an archive, and a problem if it is going on a web page.
Is my AVI file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your AVI is read straight from your own disk, converted on your machine and handed back as a 3GP. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several AVI files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate 3GP downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
