3GP to AVI converter
Turn 3GP files into AVI for free. The conversion runs entirely in your browser, so your videos are never uploaded anywhere.
How to convert 3GP to AVI
- Add your 3GP files. Drop one or more .3gp files on the box above, or tap it to pick them from your device.
- Let it convert. The first video you convert loads the converter once (about 31 MB, then cached). After that it runs on your device; a progress bar shows how far along it is.
- Download the AVI. Press Download next to each file. Nothing was sent to a server, so close the tab and it's gone.
What is a 3GP file?
3GP is the video format older mobile phones recorded in, built for tiny files over slow networks.
What is AVI?
AVI is an old Microsoft video container from the 1990s, still found on old cameras and archives.
Why convert 3GP to AVI?
3GP is great for very old phones, but low quality and little support on computers and the web. AVI is the better choice for old Windows software; keep in mind large files and poor support on phones and the web.
Will I lose quality?
AVI uses lossy compression tuned so the difference is invisible at normal use. We use high-quality settings by default.
Private by design
Most online converters upload your file to their servers. This one doesn't: the converter itself is loaded into your browser and works offline from there, so your videos never leave your phone or computer.
Questions
Is this 3GP to AVI converter free?
Yes, completely free, with no sign-up, no watermark and no daily limit.
Are my 3GP files uploaded?
No. The conversion happens inside your browser on your own device. Nothing is sent to us or anyone else.
Can I convert 3GP to AVI on iPhone or Android?
Yes, in a modern browser. Phones are slower than computers for video, and very long videos can run out of memory on older phones.
Can I convert several files at once?
Yes. Drop as many as you like; they are converted one after another and each gets its own download button.
Is there a file size limit?
No fixed limit, but your browser has to hold the whole file in memory, so files over about 2 GB may fail.
