About MOV and Opus

MOV is QuickTime; transcoding to H.264 keeps it playable everywhere.

Opus gives the best quality per bit for speech and music at low bitrates.

MOV files are read by the convertexa engine that ships with this page, so the conversion is identical whether you use this tool or the general converter. The output is produced with the same codec settings for every visitor, which means the same input always produces the same result.

Limitations

  • Only the first audio stream is used.

Frequently asked questions

How do I convert a MOV file to Opus?

Add your MOV file to the box above. convertexa detects the format from the file content, applies the MOV to Opus conversion and gives you the result to download. The whole operation runs inside your browser.

Are my MOV files uploaded anywhere?

No. The conversion runs in a sandboxed worker on your own device. Your file never leaves the browser, and nothing is stored on a server.

Is the MOV to Opus conversion lossless?

No. Opus is a re-encoded format, so some data is discarded to reach the target format. MOV is QuickTime; transcoding to H.264 keeps it playable everywhere.

Is there a size limit?

For reliable results keep the input under 300 MB. Very large files run out of memory in the browser rather than failing quietly.

Any current version of Chrome, Edge, Firefox or Safari on a desktop. The conversion engines need WebAssembly and Web Workers, both of which are standard since 2018.
