3GP to VOC Converter
FileFlip converts 3GP to VOC entirely inside your browser, using FFmpeg compiled to WebAssembly. The file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. That means no file-size limit, no queue and no account.
How do I convert a 3GP file to VOC?#
- Drop your 3GP file onto the converter at the top of this page, or click it to pick one from your computer. You can add as many as you like.
- Leave the target set to VOC and the conversion starts on its own. FileFlip downloads 30.8 MB of WebAssembly the first time and nothing after that, then runs FFmpeg on your own machine.
- Save the VOC file. Your browser writes it straight to your downloads folder, because there was never a server holding it.
Does converting 3GP to VOC lose quality?#
It depends on what is inside the file. 3GP is a container rather than a codec, so whether the VOC conversion copies the streams across untouched or re-encodes them is decided by the codecs that particular file happens to use.
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 3GP to VOC actually does to the file#
Converting 3GP to VOC runs on FFmpeg, downloads 30.8 MB of WebAssembly the first time and nothing after that, re-encodes or copies through depending on the codecs in the file, and drops encoded streams and video tracks.

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.
What is a VOC file?#
A VOC file holds audio in Creative Voice File format, the format Creative Labs introduced alongside the original Sound Blaster card in 1989 for storing digitized speech and sound effects in DOS-era games.
VOC mainly shows up today inside old DOS games and their emulation via DOSBox, where the original sound assets were never converted to a newer format.
Convert VOC to WAV to play or edit the audio in current software, since almost every modern audio tool reads WAV and very few still read VOC.
3GP to VOC 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.
