Convert WMA to MP3.
WMA is Microsoft's old audio format, fine on a Windows PC, awkward everywhere else. Convert it to MP3 so it plays on your phone, in the car, and in every app you own.

A format from the Windows Media era
.wma was everywhere when Windows Media Player ruled the desktop: ripped CDs, downloaded tracks, old voice recordings. It still plays fine on Windows, but the moment a file lands on a phone, a Mac, or a car's USB port, it tends to go quiet. MP3 is the universal default that just works.
Rescue an old library
If you've got a folder of WMA tracks from years ago, batch-convert the lot to MP3 in one go and download them back as a zip, a tidy way to move an old music collection onto modern devices.

WMA to MP3: re-encoded
MP3 is a compressed, lossy audio format, so this re-encodes the sound and the file gets smaller. Every lossy re-encode sheds a little quality, so convert from the best source you have rather than chaining conversions.

Common questions
Why won't my WMA play on my phone?+
WMA is a Microsoft format that Windows handles natively but iPhones, many Android players and car stereos don't. MP3 plays on essentially everything, so converting fixes the compatibility once and for all.
Is it free?+
Yes. Convert WMA to MP3 free. No signup and no watermark. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.
Is my file private?+
Uploads go to a private bucket, are converted, and auto-delete after 1 hour. Files never touch a third-party converter.
Will quality drop?+
Both are lossy, so this is a re-encode, but at a high bitrate the difference is inaudible for music and speech.
