Convert WMA to FLAC
Ethical Tube's free WMA to FLAC converter turns WMA audio files into FLAC, lossless compressed audio. It runs entirely in your browser, so your audio files are never uploaded, and it's free with no sign-up or watermark. The first conversion downloads the FFmpeg engine (10 MB) once, and it's cached after that.
Files are converted on your device and never uploaded.

The formats
WMA and FLAC at a glance
What is a WMA file?
WMA is Microsoft's Windows Media Audio format, used by Windows Media Player and many CD rips from the 2000s. It plays on Windows, but iPhones, Macs, and many newer devices can't play it. Songs bought from old DRM stores can't be converted. It opens in Windows Media Player and VLC. iPhone, Mac, and most Android music apps can't play it.
What is a FLAC file?
FLAC compresses audio without losing any quality, usually to about half the size of a WAV file. Music collectors and hi-res music stores use it because it keeps CD-quality or better audio bit for bit. It opens in Windows 10 and 11, Android, VLC, foobar2000, browsers, and most hi-fi players. On iPhone and Mac it plays in the Files app, QuickTime, and VLC, but the Music app can't import it.
Good to know
What changes when you convert WMA to FLAC
- FLAC is lossless, so no more quality is lost, but it can't restore what WMA compression removed, and the file gets bigger.
- The audio is saved as lossless FLAC.
- WMA files are converted with FFmpeg running in your browser.
- The first conversion downloads FFmpeg compiled to WebAssembly (10 MB). It's cached, so later visits start quickly.
- Copy-protected (DRM) files can't be converted.
- Very long videos can run out of memory, especially on phones.
FAQ
Questions, answered
Is this WMA to FLAC converter free?
Yes. It's completely free, with no sign-up, no watermark, and no limit on how many files you convert. It costs Ethical Tube nothing to run, because the conversion happens on your own device rather than on a server.
Are my files uploaded anywhere?
No. The conversion runs inside your browser with FFmpeg compiled to WebAssembly, so your files never leave your device. Once the page and the engine have loaded, it even works offline.
Does converting WMA to FLAC lose quality?
No. FLAC is lossless, so nothing is lost in the conversion. It can't add back quality that the WMA compression removed, though.
Can I convert several WMA files at once?
Yes. Add as many as you like. They're converted one after another, and you can download each FLAC file as soon as it's ready or all of them in one ZIP file.
Does it work on iPhone, Android, Mac, and Windows?
Yes, in any current browser on a computer or phone. FFmpeg runs on your processor without hardware acceleration, so long videos are much faster on a computer.
What can open a FLAC file?
Windows 10 and 11, Android, VLC, foobar2000, browsers, and most hi-fi players. On iPhone and Mac it plays in the Files app, QuickTime, and VLC, but the Music app can't import it.
Is there a file size limit?
There's no upload limit because nothing is uploaded. The practical limit is your device's memory: everyday files are fine, and a computer can usually handle recordings several hours long.
