QUICK ANSWER
Is it possible to convert 3GP to MP4?
Yes - 3GP converts to MP4.

You can do it right here with our free converter - no sign-up, and your file is deleted right after.

The fastest path is FFmpeg with a stream copy, which remuxes the file in seconds with no quality loss. The main caveat: old phone clips commonly carry AMR audio, which MP4 does not support, so the audio track usually needs re-encoding to AAC during conversion.

Why convert 3GP to MP4?

3GP was designed for 3G mobile phones and MMS messaging, so modern computers, video editors, and streaming platforms rarely play it natively. Converting to .MP4 makes old phone recordings compatible with virtually every device and editable in any video software without installing extra codecs.

Quality & what to watch

  • AMR audio is the most common problem: old phone recordings use the AMR codec, which MP4 players do not support - always re-encode the audio to AAC during conversion.
  • Output resolution stays the same as the source - 3GP clips from early phones are typically 176×144 or 352×288, and converting to MP4 does not add detail.
  • If the .3gp already contains H.264 video and AAC audio, a lossless stream copy is possible: ffmpeg -i in.3gp -c copy out.mp4.

Frequently asked questions

Does converting 3GP to MP4 lose quality?
Not if you use a stream copy - the video and audio data are moved unchanged into the new container. Re-encoding (HandBrake, VLC, or most online tools) causes a small quality reduction, though at the low resolutions typical of 3GP clips the difference is rarely visible.
Why does my converted MP4 have no sound?
The original .3gp carried AMR audio, which MP4 does not support. Re-encode the audio to AAC during conversion - our converter and the FFmpeg command above both handle this automatically.
Will converting 3GP to MP4 change the video resolution?
No - the output resolution matches the source exactly. If you want a larger frame size, you need to upscale during re-encoding, but that adds no real detail.
Does this work for `.3g2` files too?
Yes - .3g2 is the CDMA variant of the same container format and converts to MP4 using the same tools and steps.
