OGV → M4A
What changes in this conversion
- M4A opens almost everywhere, so the converted file will work on devices and programs that refused the original OGV.
- Only the audio track is kept — the video picture is discarded, so the result is far smaller than the original OGV file.
How to use
-
Add your OGV file
Drag the OGV file onto the drop area above, or click it to pick a file from your device. You can add several files at once.
-
Confirm M4A as the output
M4A 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 M4A file
When it finishes, download the M4A file. Converting multiple files gives you the option to download them together as a ZIP.

Frequently asked questions
Is converting OGV to M4A really free?
Yes. OGV to M4A conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.
Are my OGV files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so the OGV 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 OGV to M4A?
Yes — M4A 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 OGV to M4A 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.
