WMA to MP3 Converter

Runs in your browser — your files are never uploaded.

Convert Windows Media Audio to MP3. WMA turns up in old ripped CD collections and Windows-era voice recordings, and support for it has quietly disappeared — phones, Macs and most browsers will not touch it. Converting to MP3 makes those files playable again. Runs entirely in your browser using a real build of ffmpeg.

Frequently asked questions

Will DRM-protected WMA files work?+

No. Some music bought from Windows-era stores carries DRM, and those files cannot be decoded by any converter — they will fail here. Ordinary WMA files ripped from your own CDs convert fine.

Will the quality drop?+

Slightly, since this is one lossy format re-encoded to another. The output is high-quality VBR MP3 (around 190kbps), so the difference is very hard to hear on typical WMA sources.

Can I convert a whole folder at once?+

Not yet — this converts one file per run. The engine stays loaded in the tab after the first conversion, so subsequent files go through quickly.

Is my file uploaded anywhere?+

No. Once the engine has loaded, the whole conversion happens inside your browser tab.
