What is 3GP?
3GPP multimedia container — the video/audio format older mobile phones recorded to and used for MMS. The audio track inside is usually AMR or AAC. Extract it to MP3 to play the sound anywhere.
What is MP3?
The most widely used audio format. Great compatibility, small file size. Ideal for music, podcasts, and general use.
Why Convert 3GP to MP3?
3GP is the multimedia container that older mobile phones used for recording video and for MMS clips. If you've dug up old phone footage or voice clips, they're often .3gp files — and while they carry both video and audio, sometimes the audio is all you want: a voice recording, a piece of music, the sound from a memorable old clip. Converting to MP3 lets you keep just that audio in a small, portable file that plays on any modern device. There's a practical compatibility angle too: 3GP files, and the AMR or AAC audio tucked inside them, don't play reliably on today's computers and media players. Modern phones, desktop apps, and web players frequently can't open a .3gp file at all, so a recording that mattered years ago becomes stranded. Pulling the audio into MP3 rescues it — MP3 is supported everywhere, so the sound will play in any app, on any phone, and attach cleanly to any message or email. This converter reads the 3GP, drops the video stream, decodes the audio track (AMR or AAC), and re-encodes it to MP3, all with FFmpeg compiled to WebAssembly inside your browser. Nothing is uploaded, so old personal recordings stay private on your device. It's the simplest way to get usable audio out of legacy phone files without installing any software.

What is a 3GP file?
3GP is a multimedia container older mobile phones used for video recordings and MMS clips. The audio inside is typically AMR or AAC. Because .3gp isn't well supported on modern devices, extracting the audio to MP3 makes it playable everywhere.
Does this keep the video or just the audio?
It extracts only the audio and saves it as MP3; the video stream is discarded. That's exactly what you want when you're after the sound — a voice clip, music, or narration — from an old phone file.
Why won't my 3GP file play?
Many modern players and phones no longer support the 3GP container or its AMR/AAC audio. Converting the audio to MP3 — a format supported on virtually every device — fixes that so the recording plays again.
Are my files uploaded anywhere?
No. Conversion runs entirely in your browser with FFmpeg WebAssembly, so your 3GP file never leaves your device — safe for old personal recordings.
