Add your 3GP file
Drop one or more .3gp files onto the converter above, or browse for them. They load into browser memory only — nothing is uploaded, so there is no size-based pricing and no server queue.
3GP to MPEG
Pulling the soundtrack out of a .3gp video into .mpeg audio keeps what you can hear and drops the picture entirely. Free, private, and validated — the file never leaves your browser.

Pulling the soundtrack out of a .3gp video into .mpeg audio keeps what you can hear and drops the picture entirely. A .3gp file is a lightweight container defined by the 3GPP standards body for video recorded and shared on mobile phones. It packs low-bitrate video and compressed speech with minimal overhead, which made .3gp the format of MMS messages and early camera phones.
An .mpeg file holds an MPEG program stream: video and audio multiplexed together using the original MPEG-1 or MPEG-2 standards. These files come from Video CDs, DVD-authoring workflows, and older capture hardware, and they remain readable by virtually every conversion tool. For this route the practical draw is universally decodable, with all underlying patents expired and simple, robust structure that tools have parsed for thirty years — balanced against mPEG-1 and MPEG-2 need roughly twice the bitrate of H.264 for comparable quality, which is worth knowing before you commit a large batch.
Why convert 3GP to MPEG?
The usual reason to take .mpeg audio out of a .3gp file is that only the sound matters — a talk, interview, song, or podcast segment. Keeping the video stream would waste storage, and a dedicated audio file is easier to trim, tag, and play. On the source side, picture quality is poor by any modern standard; on the target side, the payoff is universally decodable, with all underlying patents expired, which is exactly what you want for handling digitized VHS or Video CD content.
3GP vs MPEG at a glance
| Aspect | 3GPP video (.3gp) | MPEG video (.mpeg) |
|---|---|---|
| Format type | Container — quality depends on the codecs and settings inside | Container — quality depends on the codecs and settings inside |
| How it stores data | iSO base media structure like MP4, but with a deliberately restricted codec list | program streams were engineered for reliable storage media, in contrast to the error-hardened transport stream used for broadcast |
| Strongest at | recovering videos from old feature phones and their memory cards | handling digitized VHS or Video CD content |
| Weak spot | picture quality is poor by any modern standard | mPEG-1 and MPEG-2 need roughly twice the bitrate of H.264 for comparable quality |
| Metadata | a small set of 3GPP-defined asset atoms for title, author, and location exists, though most recording phones never wrote them | the program stream carries essentially no descriptive metadata; the specification predates any notion of embedded titles or tags |
Pick MPEG as the output
Select .mpeg in the output menu next to each file. The menu only offers targets this engine can genuinely produce, so if MPEG is selectable, the route is real and validated.
Convert on your device
Press Convert. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded.
Verify and download
Each result is signature-checked before the download unlocks, so a failed encode can never masquerade as a valid MPEG file. Outputs keep the original filename with the .mpeg extension.
3GP to MPEG questions, answered
Will converting 3GP to MPEG lose quality?
Since 3gp is container-oriented and mpeg is container-oriented, the conversion preserves the source content exactly as stored; no additional compression pass is applied beyond what .mpeg itself requires.
Is it private to convert 3GP files here?
Yes — the .3gp file is processed inside your browser tab and never uploaded. A WebAssembly FFmpeg build demuxes the audio track and re-encodes it locally; the video stream is simply discarded. Close the tab and the file is gone from memory.
Where will the MPEG file work?
Desktop players on every operating system decode MPEG-1 and MPEG-2 program streams, and no licensing barriers remain. Browsers never adopted the format for the HTML5 video element, so web delivery requires conversion first.
Will the MPEG file be bigger or smaller than my 3GP?
Much smaller — the video stream is usually 80–95% of a .3gp file's weight, and it is discarded entirely. The remaining audio is re-encoded at the bitrate implied by your quality setting.
What happens to the metadata in my 3GP file?
This converter strips container metadata deliberately (the FFmpeg command runs with metadata mapping disabled) so exported files do not leak recording details. In the source, a small set of 3GPP-defined asset atoms for title, author, and location exists, though most recording phones never wrote them; none of it is transmitted anywhere because the file never leaves your browser.
Can I convert MPEG back to 3GP?
Yes — the reverse route exists as a separate tool. Bear in mind that round-tripping .3gp → .mpeg → .3gp is not a perfect undo when any lossy step is involved; keep your original if fidelity matters.
