Convert 3GP to FLAC
Updated Jul 2026
3GP is a video container old mobile phones used for clips and voice recordings, and FLAC is a lossless audio format used for archiving music and sound. To convert, you pull the audio track out of the 3GP file and save it as FLAC. Doing this on your own computer means the recording never has to leave your machine.

3GP vs FLAC: what actually changes
| 3GP | FLAC | |
|---|---|---|
| Contains | Video plus an audio track | Audio only |
| File size | Small, low-resolution video and compressed audio | Larger, since lossless audio takes more space |
| Audio quality | Lossy, often a low-bitrate voice codec | Lossless from this point forward, but it can't add back detail the 3GP never had |
| Compatibility | Old mobile phones, rarely playable on current devices | Any modern music player or audio software |
| Video | Present | Discarded during conversion |
When to convert, and when not to
Convert 3GP to FLAC when you have old voice memos, recordings, or clips from a phone that no longer plays 3GP files, and you want the audio saved in a format that will keep playing for years without any further quality loss.
Keep the original 3GP if the video itself matters, since converting to FLAC keeps the sound and throws away everything you'd see on screen.
Why not just use an online converter?
3GP files from old phones are often personal, a voice memo, a recorded call, a clip nobody else was meant to hear. Uploading one to an online converter sends that recording to a server you don't control. Converting on your own computer keeps it on your machine the whole time, and you can do it with your wifi off.
Questions
Does converting 3GP to FLAC lose quality?
No, FLAC is lossless, so it preserves exactly what's in the audio track. It just can't improve audio that was already recorded at low quality, which is common in old 3GP files.
What happens to the video when I convert 3GP to FLAC?
It's discarded. FLAC is an audio-only format, so the conversion pulls out the sound and leaves the picture behind. Keep the original 3GP if you want the video too.
Why convert an old 3GP file to FLAC instead of a smaller audio format?
FLAC is a reasonable choice if you're archiving something you care about and don't want to lose any more quality than the recording already has. If file size matters more than exactness, a compressed format may suit you better.
Will the FLAC file keep any information from the original 3GP?
Basic details like the recording date usually carry over if they were stored in the file, but 3GP metadata is often sparse to begin with.
Can I convert 3GP to FLAC without uploading it anywhere?
Yes. A desktop app like Morphjet converts the file locally, so the recording never travels over the internet.
