Recovering old phone recordings so they play on current devices.
3GP was built for phones on 2G and 3G networks, with tiny resolutions and heavily compressed audio. Anything recorded in it is low quality by design, and converting will not add detail that was never captured.
MP4 is the format the world settled on. It is a container rather than a codec, almost always holding H.264 video and AAC audio, and there is no device, browser, editor or social platform that refuses it. If you are not sure what to convert something to, the answer is MP4.

| Developed by | 3GPP | MPEG |
| Type | Container | Container |
| Usual codecs | H.263, AMR audio | H.264 or H.265 with AAC |
| File size | Very small, low quality | Small for the quality |
| Best suited to | Old mobile phones | Everything, honestly |
| Support | Dated | Universal |
The video is decoded and re-encoded, which costs a small amount of quality - invisible once, noticeable if you convert the same clip back and forth repeatedly. Resolution, frame rate and aspect ratio are preserved. Going from 3GP to MP4 changes the wrapper and the codec, not the footage itself.
Video takes real time. A short clip finishes in under a minute, while a full-length film can take considerably longer, because every frame has to be decoded and encoded again. Uploading a large file is usually the slowest part of all.
Your file is uploaded to our server because the conversion runs there. A cleanup task runs every hour and deletes anything older than an hour, so nothing you upload survives more than about two hours. We do not open your files, we do not keep copies, and no account is needed to use the converter.
