What is WMA?

WMA is Microsoft's audio format from the Windows Media era, still found in old ripped libraries and downloads. Outside Windows it is poorly supported, and even there the ecosystem has moved on. Converting to MP3 makes those files playable on phones, browsers, and everything else.

Common questions about WMA

What is a WMA file?
WMA (Windows Media Audio) is Microsoft's audio format from the Windows Media era, stored inside an ASF container. It was common for music ripped from CDs on Windows PCs and for downloads in the 2000s, so it still turns up in old music libraries. Outside the Windows ecosystem it is poorly supported, and even there the world has moved on to MP3 and AAC.
Why won't my WMA file play on my phone or in some apps?
WMA was built around Windows Media Player and never gained broad support elsewhere. Most phones, browsers, and non-Windows players do not decode it out of the box, which is exactly why old WMA libraries feel stuck. Converting to MP3 makes those files playable on essentially any device or app.
How do I convert WMA to MP3?
Drop your .wma file into hushvert and choose MP3. The WMA decode runs in your browser through WebAssembly, so the file never leaves your device. It is free and unlimited with no account. MP3 is the only target offered for WMA, which is usually exactly what you want: getting these files out of a Windows-only format and into one that plays everywhere.
Is converting WMA to MP3 private? Does it upload my file?
No upload. WMA to MP3 is client-side, so the whole conversion happens on your own machine. You can verify it by switching to airplane mode or watching the Network tab while it runs, and there is a live demonstration on our /privacy-proof page. This is handy when you are digitizing an old personal music collection you would rather not send to a server.
Will the audio quality drop when I convert WMA to MP3?
Most WMA files are already lossy, so converting to MP3 is a second lossy encode and there is a small change rather than a perfect copy. hushvert encodes MP3 at a high bitrate to keep that change minimal. Since WMA libraries are usually old CD rips rather than masters, MP3 at a good bitrate will sound effectively the same as the WMA you started with for everyday listening.
