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.

About the OGA format
OGA is the Ogg container's audio-only extension: the same Vorbis (or Opus/FLAC) stream as an OGG file, renamed to signal "this is music, not video". Wikipedia's audio files and old game rips commonly use it.
Functionally it is an OGG — and it inherits the same hardware-support lottery. Converting OGA to MP3 ends the guessing game on phones, car stereos and anything without an Ogg decoder.
+ Strengths
- ✓Open, royalty-free Vorbis audio
- ✓Identical quality to OGG
! Limitations
- −Extension confuses players less familiar with Ogg
- −Same hardware gaps as OGG

Frequently asked questions
Is this WMA to OGA 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 OGA?
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.
Are tags like title and artist preserved?
Tag handling varies between target formats and this conversion focuses on the audio itself. For archival copies where tags matter, keep the original file; the converted copy is for playback and sharing.
Will converting WMA to OGA reduce audio quality?
If OGA is lossless, the output contains everything the WMA file contains — no further loss is added. If OGA 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.
