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 WV format
WavPack's signature trick is the hybrid mode: encode once into a small lossy .wv plus a tiny .wvc correction file — together they are bit-exact lossless, apart the small file plays like a high-quality MP3. It also offers pure lossless and pure lossy modes in the same container.
Full WavPack files decode losslessly through ffmpeg into FLAC or WAV; hybrid correction files are handled by the original encoder only, so a .wvc alone cannot be restored.
+Strengths
- ✓Unique hybrid lossy+correction mode
- ✓Fast decode, open source
- ✓Error-robust streaming modes
!Limitations
- −Ratios slightly behind APE
- −.wvc correction files are orphaned here
- −Hardware support rare
Why convert WMA to WV?

Frequently asked questions
Is this WMA to WV 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 WV?
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.
Will converting WMA to WV reduce audio quality?
If WV is lossless, the output contains everything the WMA file contains — no further loss is added. If WV is lossy, one recompression pass is unavoidable; the quality slider controls how much. Loss that already happened in the source file can never be undone by converting.
Can I convert a whole folder of WMA files?
You can select many files at once and they are processed in a single batch. Output files land in one ZIP download when there is more than one result.
