Why convert 3GP to MP3?
3GP videos from old phones often hold voice clips and moments you want to keep. Converting 3GP to MP3 also fixes AMR sound that modern computers cannot play.
- 3GP: low quality by design.
- MP3: plays on every device.
- MP3: small files.
Phone audio in 3GP files is low bitrate, so 128 kbps MP3 is plenty and keeps the file small.

Does converting 3GP to MP3 lose quality?
Only the sound is kept and re-encoded as MP3. Video soundtracks are usually AAC at 128–256 kbps, so choosing 192 kbps or more keeps the MP3 sounding the same as the video.
How long does it take?
Fast. Only the sound is decoded, so even a long video usually converts in well under a minute.
What is a 3GP file?
3GP is a mobile video format designed for 3G phones. It keeps files tiny with low resolutions and narrow audio. Old feature phones and early smartphones recorded video as 3GP.
What is an MP3 file?
MP3 is the most widely used audio format in the world. It removes sounds people are unlikely to hear, shrinking a song to about a tenth of its CD size. At 192 kbps or higher most listeners cannot tell it from the original, and every device plays it. Its patents expired in 2017, so it is now free to use.
Frequently asked questions
Is the 3GP to MP3 converter free?
Yes, completely free, with no sign-up and no watermark. Files up to 1 GB each can be converted, and there is no daily limit.
Do you keep a copy of my files?
We never receive them. All processing happens on your device, so there is nothing for us to store or delete.
Will the MP3 sound as good as the 3GP?
Only the sound is kept and re-encoded as MP3. Video soundtracks are usually AAC at 128–256 kbps, so choosing 192 kbps or more keeps the MP3 sounding the same as the video.
Can I convert MP3 back to 3GP?
Yes, use the 3GP Converter and choose 3GP as the output.
An old 3GP from a phone plays without sound. What should I do?
The sound is probably AMR. Convert it to MP4 and the audio becomes AAC.
Can I use it on my phone?
Yes. Open the page in your phone's browser and choose a file. Phones have less memory than computers, so very large files are better converted on a laptop or desktop.
