How to convert WMA to MP3
- Add your WMA files. Drag them onto the box above or click to browse. You can add several at once.
- Pick a quality. 192 kbps suits most uses; choose 320 kbps for the best quality or 128 kbps for smaller files.
- Download. Each MP3 gets its own download button as soon as it’s ready.
What is WMA?
WMA (Windows Media Audio) was Microsoft’s answer to MP3 in the early 2000s, and many CD rips from Windows Media Player are still sitting in this format. Today most phones, Macs and web browsers can’t play WMA, which makes converting to MP3 the simplest way to keep those collections alive.
Tips
- The first WMA conversion downloads our converter engine (about 30 MB) once; after that it’s instant.
- Old CD rips were often made at 128 kbps — converting at 192 kbps keeps all the quality they have.
- Files with DRM (protected purchases from old music stores) can’t be converted.
WMA to MP3: questions
Why does the first WMA conversion take longer?
Browsers can’t decode WMA themselves, so the page downloads a WebAssembly version of FFmpeg once. It’s cached for future visits.
Can Windows Media Player convert WMA to MP3?
Only by burning and re-ripping a CD. This converter does it directly in a few seconds.
My WMA file won’t convert — why?
It is most likely DRM-protected. Protected WMA files from old music stores can’t be converted by any tool without the original licence.
Are my files uploaded?
No. Anything to MP3 converts WMA to MP3 inside your browser, so your files never leave your device.
