Turn your 3GP file into an MP4 that plays where you need it, right in your browser.
Drag and drop the file, or click to browse. Files up to 500 MB are supported, and nothing is installed.
MP4 is already selected, so there is nothing to configure. You can switch formats in the panel if you need to.
We convert on our servers, usually in under a minute. Create a free account to download the MP4, or keep editing the file in REQO.
3GP was designed to squeeze video down small enough for 3G phones. Anything recorded in it is low resolution by definition, and modern devices mostly refuse to open it.
The practical problem: Modern phones and browsers no longer support 3GP reliably. AMR audio inside is not readable by most editors. Resolution is capped so low that anything but MP4 is wasted effort.
MP4 solves that. Plays natively on every phone, browser, TV and editing app with no extra codecs. Every upload form accepts it, from YouTube and LinkedIn to Slack and email. H.264 keeps files small enough to send while still looking sharp at 1080p.
3GP came off pre-smartphone handsets, so the source resolution is low and no conversion can add detail back. What MP4 buys you is a file that modern phones, browsers and editors will actually open.
| 3GP | MP4 | |
|---|---|---|
| Container | 3GPP multimedia | MPEG-4 Part 14 |
| Typical codecs | H.263 / early H.264, AMR audio | H.264 video, AAC audio |
| Best for | Clips off pre-smartphone handsets | Sharing anywhere, uploads, web embeds |
| Plays on | Old phones and some desktop players | Every phone, browser, TV and editor |
| File size | Tiny, because the quality is tiny | Small for the quality |
Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the MP4 itself beyond the free-plan badge.
No. The conversion runs on our servers and the whole flow happens in your browser, so it works the same on Windows, macOS, Linux, iPhone and Android.
Converting re-encodes the video, so it is not bit-for-bit identical. We encode at a high quality target, which keeps the result visually indistinguishable from the 3GP on normal viewing. Converting the same file back and forth repeatedly will eventually show, so keep your original.
Up to 500 MB per file. For anything bigger, trim or compress it first, both are free tools here.
Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
