## Questions & answers

### What even is a 3GP file?

3GP is the mobile video format from the pre-smartphone era, designed for tiny files over slow networks. If you rescued clips off an old Nokia or a memory card from the 2000s, this is what they are.

### Do these old clips get uploaded to convert them?

No. Conversion runs in your browser, your video never leaves your device, and nothing is stored.

### Why does the converted video still look blurry?

3GP clips were recorded at very low resolutions to fit early phone storage. Conversion preserves every pixel that exists, but it cannot invent detail that was never recorded.

### My 3GP won't convert, what now?

The oldest 3GP clips use codecs like H.263 and AMR that browsers cannot decode, so those files need a desktop encoder like HandBrake. 3GP files recorded as H.264 convert right here.

### Will the sound come through?

When the browser can decode the clip, the audio track comes through as AAC inside the MP4, which every modern player handles.

### Need a different output format?

Pick WebM, MOV, or MKV in the [video format converter](/tools/video-format-converter).

## Stop editing one clip at a time.

OpenClip finds your best moments, reframes them face-aware for every platform, writes the captions, and posts them. One upload, a week of content.
