What changes in this conversion
- OPUS is a newer format — check that the software or device you are sending it to supports it before switching.
- Only the audio track is kept — the video picture is discarded, so the result is far smaller than the original DIVX file.
How to use

Add your DIVX file
Drag the DIVX file onto the drop area above, or click it to pick a file from your device. You can add several files at once.
-
Confirm OPUS as the output
OPUS 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 OPUS file
When it finishes, download the OPUS file. Converting multiple files gives you the option to download them together as a ZIP.

Frequently asked questions
Is converting DIVX to OPUS really free?
Yes. DIVX to OPUS conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.
Are my DIVX files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so the DIVX file never leaves your device. That is also why it works without an internet connection once the page has loaded.
Will the OPUS file open everywhere?
OPUS is a newer format. Current browsers and phones handle it, but older desktop software may not — keep the original DIVX if you have to send it to someone on an old machine.
Does the picture disappear when I convert DIVX to OPUS?
Yes — OPUS 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 DIVX to OPUS 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.
