Why Convert 3GP to MP3?
3GP was designed for early mobile phones, bundling low-bitrate audio and video together — but often the audio (a voice memo, a song, ambient recording) is the only part actually worth keeping from an old 3GP file.
MP3 is the universal audio format, playable everywhere, letting you extract and keep just the sound without needing a video player or worrying about 3GP compatibility on modern devices.
This conversion is common for old phone recordings — voice memos, concert clips, or short videos — being converted into a simple audio file for easier storage and playback.

Frequently Asked Questions
Will the audio quality be as good as the original?
The extracted MP3 reflects the quality of the audio already embedded in your 3GP file — since 3GP audio was typically encoded at low bitrates for mobile storage, don't expect studio quality, just a faithful copy of what was recorded.
Will this work on any 3GP file?
Yes, as long as the source file has an audio track — standard 3GP recordings convert reliably.
Do I need any special software installed?
No — the conversion happens entirely on our servers.
Can I extract audio from a 3GP file with no sound?
No — if the source video has no audio track, there's nothing to extract.
Is there a file size limit?
50MB free, 100MB for registered accounts.
