Why Convert 3GP to MP4?

3GP is the video your phone recorded fifteen years ago, a low-resolution container built to squeeze clips onto 3G networks and tiny memory cards. Modern editors and players treat it as a curiosity.

Converting to MP4 hands you a file today's software actually opens, ready to trim, upload, or archive.

Frequently Asked Questions

Can I convert 3GP to MP4 in the browser?
No. This legacy mobile container runs in the desktop app through FFmpeg. Conversion happens locally on your Mac; nothing is uploaded.
Will the MP4 look sharper than the 3GP?
No. 3GP files are low resolution by design, and converting cannot invent detail the phone never recorded. The MP4 just plays in modern software the 3GP struggles with.
What is the difference between 3GP and 3G2?
3GP came from the GSM phone world and 3G2 from CDMA carriers; they are close cousins with slightly different codec sets. FFmpeg reads both and writes a standard H.264 MP4.
Does the audio track come across?
Yes. The AMR or AAC audio in the 3GP is re-encoded to AAC and kept in sync in the MP4.
Is my file still private in the desktop app?
Yes. The desktop app converts with native engines on your Mac and works offline after a one-time activation check. Nothing is uploaded, in the browser or on desktop.

Digitizing an old phone-video collection?
