What usually goes wrong

About the MKA. An MKA can hold anything, so what you get from converting depends on the codec that was inside it.

About the OPUS. Opus at 64 kbps sounds better than MP3 at 128, so the bitrate you are used to is roughly double what you need here.

How to convert MKA to OPUS

  1. Add your MKA file. It is read from your disk and stays there.
  2. Check the settings. The output format is already set to OPUS.
  3. Press convert and the OPUS file is saved back to your device.

Questions

How do I convert MKA to OPUS?

Open this page, add your MKA file, and press convert. The file is decoded and re-encoded by your own browser and saved back to your device. Nothing is uploaded.

Is this MKA to OPUS converter free?

Yes, completely. There is no account, no sign-in, no watermark and no daily limit, because there is no server doing the work. Your own device does it.

Are my files uploaded anywhere?

No. There is no upload endpoint. The conversion runs inside this browser tab, so your file never leaves your device. You can open your browser's network panel and watch: nothing carrying your file is sent.

Is there a file size limit?

No fixed limit. Because the work happens on your machine there is no server quota. The only ceiling is your own device's memory, which for video means very large files may be slow.

Will converting to OPUS lose quality?

OPUS is a lossy format, so some detail is discarded. The quality control on this page decides how much. The default is set high enough that most people cannot see the difference.

Can I convert several MKA files at once?

Yes. Add as many as you like and they are converted one after another, then offered as a single ZIP.
