Convert 3GP to MP4
Updated Jul 2026
3GP is the compressed video format built for old mobile phones on slow networks, and MP4 is the video format almost everything else opens today. To convert 3GP to MP4, open the file in a converter and export it as MP4. Doing this on your own computer means the old clip never has to leave your machine.

How to convert 3GP to MP4

- Convert. The MP4 is written next to the original, and nothing leaves your machine.
3GP vs MP4: what actually changes
| 3GP | MP4 | |
|---|---|---|
| Opens everywhere | No, mostly old phones and a handful of players | Yes, plays on virtually any device or app |
| File size | Very small, built for slow mobile networks | Larger, though still efficient |
| Quality | Low, made for tiny phone screens | Same as the source, no quality is added back |
| Editing support | Poor, few editors open 3GP directly | Wide, nearly every video editor works with MP4 |
| Typical resolution | Low, often under 480p | Any resolution, including the original if it's already low |
When to convert, and when not to
Convert 3GP to MP4 when you want to watch old phone videos on a modern computer, TV, or app, share them with someone, or open them in a video editor.
Keep the 3GP original if it's just sitting in a backup somewhere and you never plan to open it again, since the file is already about as small as it gets and converting won't add back any detail the old phone never captured.
Why not just use an online converter?
Old 3GP clips are often personal, family videos, kids growing up, moments shot on a phone that's long gone. Sending one through an online converter means that footage sits on a stranger's server, even if only for a few minutes. Converting on your own computer keeps the video, and whatever it shows, on the machine you already trust.
Questions
Does converting 3GP to MP4 lose quality?
Not really. 3GP video is already heavily compressed for old mobile networks, so converting to MP4 mostly just repackages it. There can be a very small re-encoding loss, but it isn't something you'd notice.
Will the video and audio still be in sync after converting?
Yes. A straightforward 3GP to MP4 conversion keeps the video and audio tracks together and in sync. If the original clip already had sync issues, converting won't fix them.
Why won't my phone or computer play 3GP files anymore?
3GP was built for feature phones and early smartphones from the 2000s and early 2010s. Most current devices and apps dropped support for it once MP4 became the standard, so old clips can end up stuck and unplayable.
Can I convert 3GP to MP4 without uploading the file anywhere?
Yes. A desktop app like Morphjet converts the file on your own computer, so it never has to travel over the internet.
Will the converted MP4 look different from the original?
No. The resolution and quality stay the same as the source 3GP, MP4 is just a far more widely supported way of packaging that same video.
