How to convert M4A to 3GP files online?

Upload your M4A file by clicking the upload button. Select 3GP as the output format, choose AMR or AAC codec and adjust bitrate if desired. Click 'Convert' and then download the completed 3GP file to your device.

Why convert M4A to 3GP instead of keeping M4A?

3GP is a 3GPP format tailored for older mobile phones and MMS messaging. It compresses audio with AMR to dramatically reduce file size, making it easier to share via MMS or store on limited-capacity devices. While M4A offers better audio quality, converting to 3GP ensures playback on legacy devices.

What happens to audio quality and settings when converting M4A to 3GP?

The original M4A (AAC) audio is re-encoded. Using AMR reduces bitrate to 4.75–12.2 kbps and sample rate to 8/16 kHz, cutting file size but discarding high-frequencies. If you select AAC in the 3GP container, quality up to 128 kbps/48 kHz is preserved, but compatibility with older phones depends on their supported codecs.
