WMA to XZ Converter
Processing entirely on your device — large files may take a moment.
Windows Media Audio and XZ Compressed File exist for different jobs: WMA is Microsoft’s Windows Media audio format, still found in old music collections and voice recorders. Unpack XZ into ZIP/TAR for tools that cannot read LZMA2.
Because the whole conversion happens on your device, it is instant, unlimited and genuinely private — no accounts, no watermarks, no files on anyone's server. Multiple files are converted in one go.

About the WMA format
WMA (Windows Media Audio) is Microsoft's MP3 competitor from 1999, best known for DRM-protected download stores in the 2000s. The family spans standard lossy WMA, WMA Pro (up to 24-bit/96 kHz) and WMA Lossless. On Windows it integrated seamlessly; everywhere else it required goodwill.
With Microsoft's own services having moved to AAC, WMA today is a conversion source: old music libraries and ripped CDs get converted to MP3/M4A/FLAC and the format is retired. WMA Lossless files should go to FLAC to preserve their losslessness.
+Strengths
- ✓Native Windows playback and tagging
- ✓WMA Lossless preserves bit-perfect audio
!Limitations
- −Non-Windows support is poor
- −Ecosystem abandoned by its creator
- −DRM-legacy files may be unplayable
About the XZ format
XZ wraps the LZMA2 algorithm: the best ratio of the common Unix compressors, which is why distribution packages and source releases pick it when bandwidth matters more than CPU.
Windows Explorer and many cross-platform tools cannot open it — unpacking to ZIP or TAR makes the payload portable.
+Strengths
- ✓Highest common ratio
- ✓Standard for Linux packages
- ✓Integrity checks built in
!Limitations
- −Memory-hungry at high settings
- −Sparse support outside Linux

Frequently asked questions
Is this WMA to XZ converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Is there a file size limit for WMA to XZ?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
What about folders and directory structure?
The full directory tree is preserved: folders stay folders, and deep paths arrive exactly as they were packed in the WMA file.
Are the files inside my WMA archive modified?
No. Contents are unpacked in memory and repacked into XZ byte-for-byte — the conversion changes the container, never the files inside it.
