3GP to MP4 Converter

Convert old 3GP phone clips into MP4 you can actually play, edit, and share today - privately in your browser.

About this converter

3GP is the compact video format that older mobile phones used to record and send clips over early mobile networks. It keeps files tiny with codecs like H.263 or MPEG-4 Part 2 and AMR audio, but those formats are rarely supported by modern apps and editors.

Converting 3GP to MP4 re-encodes the video to H.264 and the audio to AAC, producing a file that plays on current phones, computers, and websites - and that you can edit normally.

Worth setting expectations: converting cannot add detail that the original low-resolution 3GP never captured. The MP4 will be more compatible, not sharper than the source.

3GP to MP4: good to know

3GP is usually low resolution; the MP4 will be compatible but no sharper than the original footage.
Audio is converted from AMR to AAC so it plays in standard players.
Great for digging old camera-phone memories out of an unplayable format.

Frequently asked questions

How do I convert 3GP to MP4?

Drop your 3GP file above, make sure MP4 is the output, and click Convert, then Download. It all runs on your device.

Will converting 3GP to MP4 improve the quality?

No - conversion cannot add detail that was never recorded. The result is far more compatible than a 3GP, but it will look about the same as the original low-resolution clip.

Why won't my 3GP files play on my computer?

3GP uses older mobile codecs (H.263, AMR audio) that many modern players do not include. Converting to an H.264/AAC MP4 fixes that.

Can I convert several old phone videos at once?

Yes. Drop multiple 3GP files in together and download the converted MP4s as a ZIP.

Are my files uploaded?

No. Everything is converted locally in your browser - your clips never leave your device.
