WMA
Windows Media audio
WMA is Microsoft's answer to MP3 from 1999. Music ripped with Windows Media Player is often WMA, and little outside Windows plays it.

How to convert WMA to MP3
Add your WMA audio files
Drop WMA files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.
MP3 is already chosen
Press Convert. Open Options first if you want to change the defaults. The work happens in this tab.
Download
Save the MP3, or download everything as one ZIP if you converted several files.
Why ToAny
Private by construction
The WMA to MP3 converter is part of this page and runs inside your browser. Your audio files are never sent to ToAny or to anyone else.
No upload, no queue
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
Free, without an account
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
WMA to MP3: what to expect
Music ripped years ago with Windows Media Player is WMA, a format phones, Macs and most current players ignore. MP3 plays everywhere. Copy-protected (DRM) WMA files cannot be converted.
The defaults suit most files. Under Options you can choose the bitrate and trim the start and end.
This pair uses the compatibility engine, ffmpeg built for the browser, because WMA is not handled by the browser's built-in codecs. It is a one-off download of about 10 MB that the browser keeps, it is slower than the built-in codecs, and it takes files up to 1 GB. MP3 is written at 192 kbps unless you choose another bitrate.
WMA vs MP3
MP3
MP3 audio
MP3 is the audio format everything plays. It shrinks audio to roughly a tenth of its uncompressed size by discarding sound most listeners cannot hear. Newer codecs are more efficient, but nothing matches its compatibility.

Questions
Are my audio files uploaded anywhere?
No. The WMA to MP3 conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
Does converting WMA to MP3 reduce quality?
MP3 is a lossy format, so a small amount of detail is traded for a smaller file. At the default setting the difference is hard to notice. You can choose the bitrate under Options.
Can I convert several WMA files at once?
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
How do I convert WMA to MP3 on Windows, Mac, iPhone or Android?
The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the WMA file, press Convert and save the MP3. There is nothing to install.
Is there a file size limit?
Yes. WMA to MP3 runs on the compatibility engine, which takes files up to 1 GB, and a long clip takes a while because it is slower than the browser's built-in codecs. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
