Convert 3GP to MP4
3GP is the format old phones recorded video in, and modern players, editors and social platforms often refuse it. This transcodes a 3GP to a standard H.264 MP4 with WebCodecs in your browser, so the clip plays and uploads everywhere — and the file never leaves your device.
Runs entirely in your browser — your file is never uploaded.

Frequently asked questions
Will an old 3GP clip still work?
If the video uses H.264 (most later 3GP files do), yes — it transcodes to MP4 cleanly. Very old 3GP using the H.263 codec is the exception the browser may not decode; those are rare now.
Is the video uploaded?
No. The transcode runs with WebCodecs on your device, so the video never leaves the browser — no account, no quota, no size limit. Chrome, Edge and Firefox work best.
