02

03
Download the MP3
Download each MP3, or a whole folder as one ZIP.
3GP
3GP is the video format of 2000s mobile phones, with small, low-bitrate video and AMR or AAC sound.
MP3
MP3 is the most widely supported compressed audio format, playing on virtually every phone, car stereo and computer.
FILE FORMATS
SOURCE
The 3GPP group defined 3GP for MMS messages and phone cameras on 3G networks. Nokia, Sony Ericsson, Samsung and early Android phones recorded 3GP clips with H.263, MPEG-4 or H.264 video and AMR or AAC sound, often at 176x144 or 320x240. Many of those clips survive in old phone backups and memory cards.
TARGET
MPEG-1 Audio Layer III has been the universal music format since the 1990s. It compresses audio by removing sounds the ear is unlikely to hear, so a song takes a few megabytes instead of tens. ID3 tags carry the title, artist and album art, and every phone, browser, car stereo and editor plays it.

USE CASES
When the sound from an old phone clip matters more than the picture.

Transcription tools accept MP3. Pull the sound from a 3GP interview clip.
Clear space while keeping the sound
Keep MP3s of clips where only the audio matters.
Listen in the car or on a music player
MP3s play on players that can't open 3GP video.
Use a clip's audio in a new video
Import the MP3 into a video editor as background audio or narration.

Old MMS videos were 3GP. Share the sound as an MP3 by email or chat.

Collect voices and moments from old phone videos into one audio folder.
Digitize a memory card in one batch
Convert every 3GP clip from a card at once.
SUPPORTED FILES
3GP clips from feature phones and early smartphones are supported.
Most phone 3GP clips use AMR speech audio, which converts directly.
3GP files from later phones with AAC audio convert the same way.
Files from the classic feature phones of the 2000s.
3GP clips from early smartphones and messaging apps.
Upload many 3GP clips and download the MP3s together as a ZIP.
TROUBLESHOOTING
Old phone audio has limits that carry into the MP3.
01
Phones recorded 3GP sound at low quality, often 8 kHz AMR. The MP3 keeps what was recorded and can't add detail.
02
If the sound started after the picture, the gap is kept as silence so the MP3 stays in sync with the original timeline.
03
Some clips were recorded with the microphone off. There is no sound to extract.
04
Sound ends where the recorded audio ends. A damaged clip gives only the audio that can be decoded.
05
Copy it to the phone's storage or a computer first, then upload it here.
06
Check that the file is a real 3GP clip and not a renamed 3G2 or MP4. Try the matching converter if it is.
VLC, Audacity with its FFmpeg add-on and FFmpeg itself can pull sound out of a video once installed. dragdropdo is built for turning 3GP into MP3 quickly, from any device.
