Convert 3GP to AAC
Updated Jul 2026
3GP is a video format used by older mobile phones, and it stores a low-bitrate voice audio track alongside the picture. To convert 3GP to AAC, you pull out that audio track and re-save it as AAC, the audio format Apple devices and streaming services expect. You can do this on your own computer without uploading the file anywhere.

3GP vs AAC: what actually changes
| 3GP | AAC | |
|---|---|---|
| What it holds | Video and audio together | Audio only |
| Typical audio quality | Low, compressed for voice calls over cellular networks | Higher, built for music and general listening |
| File size | Larger, because it includes the video track | Much smaller, since only the audio remains |
| Compatibility | Mostly old mobile phones and legacy messaging apps | Wide support, Apple devices, streaming apps, and most modern software |
| Common use today | Rarely used outside archived phone videos | Standard format for music libraries and podcasts |
When to convert, and when not to
Convert 3GP to AAC when you only care about the sound in an old phone video, a voice memo, a recorded call, or a video message, and you want it as a normal audio file you can play on a phone, in a car, or in a music app.
Keep the original 3GP if you still need the picture, since converting to AAC throws the video away and keeps only the sound.
Why not just use an online converter?
3GP files often come from personal phone videos, voice messages, or recorded calls, the kind of thing you wouldn't want sitting on someone else's server. An online converter has to upload the file before it can pull out the audio, which means a copy of your video passes through a stranger's system even though you only wanted the sound. Converting on your own computer keeps that video, and whatever it shows or says, on your machine the whole time.
Questions
Does converting 3GP to AAC lose quality?
The audio quality is set by the original 3GP file, which usually comes from a phone camera or voice call and wasn't recorded at high fidelity. AAC won't add quality back, but it holds what's there efficiently, so you won't lose anything further beyond a small re-encoding step.
What happens to the video when I convert 3GP to AAC?
It's discarded. AAC is an audio-only format, so the conversion keeps the sound and drops the picture entirely. If you need the video too, keep the 3GP or convert it to a video format instead.
Does the AAC file keep the original recording date?
Sometimes. 3GP files carry limited metadata to begin with, so what survives the conversion depends on what the phone recorded in the first place. Don't count on song-style tags like artist or album, since 3GP was never built to hold those.
Can I convert 3GP to AAC without uploading the file?
Yes. A desktop app like Morphjet does the extraction and conversion on your own computer, so the video and its audio never get sent anywhere.
