How to convert 3GP to MP4

  1. Upload one or more .3gp videos, up to 1 GiB per file.
  2. Keep the preset MP4 and H.264 output, or adjust quality and resolution.
  3. Check the preview, then download each MP4 result.

Format and limits

The converter processes files on the server. It accepts video in a 3GP container, but unsupported or damaged video and audio streams can fail. Re-encoding can increase file size or reduce quality; keep the original until you check the MP4.

Common questions

Will changing 3GP to MP4 improve the original picture?

No. H.264 MP4 can improve playback compatibility, but it cannot restore detail that was missing from the 3GP recording.

Can I upload a 3GP file with no video track?

No. This tool needs a readable video track to create an MP4 video.
