How to convert AVI to 3GP
Add your AVI videos
Drop AVI files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
3GP is already chosen
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab and can take a while for large files.
Download
Save the 3GP, or download everything as one ZIP if you converted several files.

The AVI to 3GP converter is part of this page and runs inside your browser. Your videos are never sent to ToAny or to anyone else.
No upload, no queue
Nothing has to travel to a server and back, so work starts the moment you press Convert. How long it takes depends on your device and the size of the file.
Free, without an account
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
AVI to 3GP: what to expect
AVI does not play on phones or in browsers, and files are large for their quality. 3GP makes very small files that old phones can play. AVI is at home in old Windows software and capture devices; 3GP is the usual choice for video from older mobile phones.
The defaults suit most files. Under Options you can lower the resolution, trade quality against file size, remove the sound and trim the start and end. This is demanding work for a browser: a long or high-resolution file can take several minutes, and your device does all of it, so keep the tab open.
This pair uses the compatibility engine, ffmpeg built for the browser, because AVI is not handled by the browser's built-in codecs. It is a one-off download of about 10 MB that the browser keeps, it is slower than the built-in codecs, and it takes files up to 1 GB.
AVI vs 3GP
3GP
3GP video
3GP is a slimmed-down relative of MP4 designed for 3G-era mobile phones, with low resolutions and small files. Old phone videos and MMS clips are usually 3GP.

Questions
Are my videos uploaded anywhere?
No. The AVI to 3GP conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
Does converting AVI to 3GP reduce quality?
It depends on what is inside the AVI. When its video and audio are already in a form 3GP can hold, they can be carried over without being compressed again. Otherwise they are re-encoded, which costs a little quality. Under Options you can favour quality or a smaller file.
Can I convert several AVI files at once?
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
How do I convert AVI to 3GP on Windows, Mac, iPhone or Android?
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the AVI file, press Convert and save the 3GP. There is nothing to install.
Is there a file size limit?
Yes. AVI to 3GP runs on the compatibility engine, which takes files up to 1 GB, and a long clip takes a while because it is slower than the browser's built-in codecs. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
