What changes in this conversion

  • Both WMA and OGG are lossy, so re-encoding discards a little more audio detail on top of what was already lost. Converting once is fine; repeating it many times is not.

How to use

  1. Add your WMA file

    Drag the WMA file onto the drop area above, or click it to pick a file from your device. You can add several files at once.

  2. 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.

  3. Run the conversion

    Press the convert button. Audio decodes and re-encodes in your browser — a normal song finishes in a few seconds.

  4. 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 WMA to OGG really free?

Yes. WMA to OGG conversion is completely free with no signup, no watermark, and no daily limit on the free plan for ordinary use.

Are my WMA files uploaded to a server?

No. The conversion runs entirely inside your browser using WebAssembly, so the WMA file never leaves your device. That is also why it works without an internet connection once the page has loaded.

Is there a file size limit for WMA 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.
