How to convert 3GP to MP3

    Copy the .3gp files from the old phone or its memory card to your computer, then drop them onto the page.

  2. Convert them to MP3

    Choose MP3 and click Convert to MP3. AMR or AAC phone audio is turned into a 192 kbps stereo MP3.

Old phone audio, saved for good

3GP was the video format of feature phones and early Android phones. The clips are small and low resolution, with AMR or AAC sound, and many of today's apps won't open them. MP3 is a safer format to keep them in for years.

Adapterry writes the first audio track as a 192 kbps, 48 kHz stereo MP3. Several 3GP clips are joined into one MP3 in list order, so a handful of short voice messages becomes one file you can play straight through.

Questions and answers

Can I put all my old 3GP voice clips in one MP3?

Yes. Add them all, put them in the order you like and click Merge & convert to MP3. Each clip plays after the last.

Will the MP3 sound clearer than my old 3GP clip?

No. Old phones recorded sound at low quality, and the MP3 keeps it as it was. Saving at 192 kbps simply avoids losing any more.

My phone saved a 3GP without sound. Will it convert?

No. A clip with no audio track can't become an MP3. Adapterry shows a message instead of making a silent file.

Does AMR audio from a flip phone work?

Yes. AMR and AAC sound in 3GP files are both read and turned into a standard MP3.

Can I hear the 3GP audio before downloading?

Yes. The finished MP3 plays on the page, so you can check it is the clip you wanted, then download it.
