What changes in this conversion
- Only the audio track is kept — the video picture is discarded, so the result is far smaller than the original 3GP file.
How to use
-
Add your 3GP file
Drag the 3GP file onto the drop area above, or click it to pick a file from your device. You can add several files at once.
-
Confirm OGG as the output
OGG is already selected as the output format on this page. You can pick the bitrate — higher keeps more of the sound, lower makes a smaller file.
-
Run the conversion
Press the convert button. Video is re-encoded frame by frame on your own machine, so a long clip can take several minutes. The tab has to stay open.
-
Download the OGG file
When it finishes, download the OGG file. Converting multiple files gives you the option to download them together as a ZIP.

Frequently asked questions
Is converting 3GP to OGG really free?
Yes. 3GP to OGG conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.
Are my 3GP files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so the 3GP file never leaves your device. That is also why it works without an internet connection once the page has loaded.
Does the picture disappear when I convert 3GP to OGG?
Yes — OGG is an audio format, so only the soundtrack is extracted. The video track is dropped, which is usually the point when you want just the audio.
Is there a file size limit for 3GP to OGG conversion?
The free plan handles files up to 200MB. Because processing happens on your own device, very large files depend on your computer's memory rather than a server quota.
