Audio Format Comparison

WMA vs FLAC: Windows Media Audio vs Universal Lossless

WMA comes in two very different versions: WMA Standard (lossy) and WMA Lossless. Comparing them to FLAC means two different discussions. WMA Standard vs FLAC is lossy vs lossless. WMA Lossless vs FLAC is Apple vs Windows lossless — and FLAC wins on every practical metric except that WMA Lossless plays natively on Windows without additional software.

Quick Verdict

Use WMA when…

Use WMA only for Windows-specific distribution where you're forced to by platform or legacy system requirements. WMA has no technical advantage over FLAC or AAC.

Use FLAC when…

Use FLAC for all lossless audio archiving and cross-platform use. FLAC is universally supported on Android, Linux, Mac, Plex, Jellyfin, Roon, and every non-Windows player — with better compression than WMA Lossless and zero proprietary lock-in.

Frequently asked questions

Can Windows Media Player play FLAC files?

Windows Media Player (classic WMP 12 on Windows 7/8/10) does not support FLAC natively. Windows 11's new Media Player app plays FLAC natively. For FLAC on Windows: use foobar2000 (best FLAC player), VLC (universal), or Groove Music/Windows Media Player with the FLAC codec installed. FLAC works on Windows — it just doesn't use Windows Media Player's native decoder.

Is FLAC better than WMA Lossless?

FLAC is more practical: it compresses slightly better, is an open standard, and is supported on every platform. WMA Lossless has no advantages over FLAC except native Windows playback in older Windows Media Player. For new archives: always use FLAC. For existing WMA Lossless content: convert to FLAC for future-proof compatibility.

What happened to WMA's market share?

WMA peaked around 2003–2010 during the Windows Media Player era and the original Zune player. It's been in decline since Apple's AAC (via iTunes) and the open-source community's FLAC became the standards. Streaming services (Spotify, Apple Music, Amazon Music) use AAC or proprietary formats. New music players default to FLAC for lossless and AAC/Opus for lossy. WMA is now a legacy format.
