What is WMA?

Windows Media Audio (.wma). WMA is Microsoft's Windows Media audio format from the Windows Media Player era. Windows plays it, but phones, Macs and many music apps do not, so WMA libraries are usually converted to MP3 or AAC.

Common use: Older Windows music libraries

Output format

What is ALAC?

Apple Lossless Audio Codec (.alac). ALAC is Apple's lossless codec: like FLAC it decodes to exactly the original audio, at roughly half the size of WAV. Apple released it as open source in 2011; iTunes, Apple Music and iPhones play it natively.

Common use: Lossless music on Apple devices

Questions about WMA to ALAC

Is converting WMA to ALAC free?
Yes, one file at a time: the converter on this page runs in your browser, files up to 100 MB, no sign-up. The Filoshi desktop app ($29 once, for Windows) converts many files at once and has no size limit.
Does converting WMA to ALAC lose quality?
No further loss: ALAC keeps exactly what is decoded from the WMA file. It cannot bring back detail that WMA's lossy compression already removed, and the ALAC file is usually larger.
Is my WMA file uploaded anywhere?
No. The converter on this page runs in your browser with FFmpeg compiled to WebAssembly; your WMA file is read and converted on your device and never sent to a server. The desktop app works the same way, offline.
Has WMA to ALAC been tested?
Yes. WMA to ALAC is one of the 1,841 conversions that passed Filoshi's automated test matrix on Windows 11.
Can I convert many WMA files at once?
Yes, in the desktop app. Drop as many WMA files as you like on the window, pick ALAC once for all of them, and each file shows its own progress. The new files appear next to the originals, which are never changed.
