3GP Converter
FileFlip converts 3GP files into 31 other formats entirely inside your browser, using WebCodecs and FFmpeg compiled to WebAssembly. The 3GP file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. There is no file-size limit and no account to create.
How do I convert a 3GP file?#
- Drop your 3GP file onto the converter at the top of this page, or click it to pick one from your computer.
- Choose the format you want out of it. FileFlip downloads the engine that conversion needs, once, and your browser caches it.
- Conversion starts the moment you pick the format, and the result is yours to download. The work happens in this tab, so nothing is uploaded and nothing is queued.
Is it safe to convert 3GP files online?#
Yes, because nothing is uploaded. FileFlip converts 3GP files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.

What is a 3GP file?#
A 3GP file holds video and audio in the multimedia container the 3GPP standards body defined for GSM-lineage mobile phones, a stripped-down MPEG-4 Part 12 structure sized for slow cellular links.
There's rarely a reason to keep new video as 3GP; it matters mainly for footage already recorded that way on an older phone.
Convert 3GP to MP4 to get footage playing smoothly on current phones, computers, and browsers, none of which prioritize 3GP support anymore.
The 3GP file format reference covers the specification, the programs that open one, and what each conversion keeps or drops.
3GP questions people ask#
What produces a 3GP file?
3GP files come from older GSM-lineage mobile phones recording video, from MMS video messages, and from early smartphone camera apps before MP4 became the default. Feature phones from the 2000s and early 2010s are the most common source of 3GP footage still around.
Why won't my 3GP file play?
Recent versions of iOS and some desktop software dropped native 3GP support, and files using AMR audio specifically fail in players and editors that don't include an AMR decoder. VLC plays nearly all 3GP files directly, AMR audio included.
What should I convert a 3GP file to?
Convert 3GP to MP4 for playback on any current device. MP4 carries the same footage without the low-bitrate ceiling and codec gaps that made 3GP awkward outside of old phones.
Is 3GP the same as MP4?
3GP is a cut-down variant of the same MPEG-4 Part 12 family MP4 belongs to, built for older phones and slow mobile networks with lower resolution and bitrate limits. An MP4 player can often open a 3GP file, but the reverse isn't guaranteed since MP4 supports codecs and features 3GP doesn't.
