WMA to OGG Converter
Drop a WMA file to inspect its metadata in your browser, choose an OGG Vorbis quality level, and copy a ready-to-run FFmpeg command — nothing is uploaded.
Inspect WMA Metadata
Drop a WMA (or any audio) file to read its properties. Nothing is uploaded.
FFmpeg Command Generator
ffmpeg -i input.wma -c:a libvorbis -q:a 4 -map_metadata 0 output.ogg
Install FFmpeg free at ffmpeg.org.
Replace input.wma with your actual filename.
Batch convert (Linux / macOS)
for f in *.wma; do ffmpeg -i "$f" -c:a libvorbis -q:a 4 -map_metadata 0 "${f%.wma}.ogg"; done
Batch convert (Windows PowerShell)
Get-ChildItem *.wma | ForEach-Object { ffmpeg -i $_.FullName -c:a libvorbis -q:a 4 -map_metadata 0 ($_.BaseName + ".ogg") }
GUI alternatives
- VLC Media Player — free, cross-platform; use Media > Convert/Save and select OGG Vorbis as output format
- fre:ac — free, open-source, Windows / macOS / Linux, supports WMA input and OGG Vorbis output
- Audacity — free, open-source; import WMA (requires FFmpeg library), export as OGG Vorbis

OGG Vorbis uses variable bitrate — estimates are based on typical average kbps per quality level. Actual size may vary 10–20%.
OGG Vorbis Quality Reference
| Quality | Avg. kbps | Size / min | Best For |
|---|---|---|---|
| -q:a 2 | ~80 kbps | ~0.6 MB | Voice, podcasts, speech |
| -q:a 4 | ~128 kbps | ~0.9 MB | General music listening |
| -q:a 6 | ~192 kbps | ~1.4 MB | High-quality music, games |
| -q:a 8 | ~256 kbps | ~1.9 MB | Audiophile OGG, archival |
OGG Vorbis at quality 4 is generally equivalent in perceptual quality to MP3 at 128 kbps, but OGG typically sounds slightly better at the same target bitrate.
WMA vs. OGG Vorbis — At a Glance
WMA (Windows Media Audio)
- Good compression at low bitrates
- Native on Windows, Xbox, and older portable devices
- Proprietary Microsoft format — limited cross-platform support
- Not supported on Linux players or most game engines natively
OGG Vorbis
- Free, open, and royalty-free — no patent restrictions
- Preferred by Linux, Godot, Kodi, and open-source ecosystems
- Slightly better audio quality than MP3 at equivalent bitrate
- Not supported natively on iOS or iTunes / Apple Music
Summary
Drop a WMA file to inspect its metadata in your browser, choose an OGG Vorbis quality level, and copy a ready-to-run FFmpeg command — nothing is uploaded.
How it works
- Drop a WMA file onto the inspector panel (or click to browse).
- The Web Audio API reads the file sample rate, duration, and channel count locally in your browser.
- Choose an OGG Vorbis quality level — quality 4 is a solid general-purpose choice; quality 6-8 is better for music.
- Optionally enable the -map_metadata flag to copy artist, title, and album tags from the WMA source.
- Copy the generated FFmpeg command and run it in your terminal.
- Verify the output OGG file in a media player before deleting the original WMA.
Use cases
- Convert a WMA music library to OGG Vorbis for Linux desktop players such as Rhythmbox or Clementine.
- Prepare audio assets for open-source games and game engines such as Godot that prefer OGG.
- Replace proprietary WMA tracks with royalty-free OGG files for open-content or web projects.
- Transfer WMA files from Windows Media Player into a Linux or Android-native OGG workflow.
- Batch-convert an entire WMA album to OGG using a single shell loop.
- Estimate the output OGG file size at different quality levels before committing to a large batch.
- Generate a ready-to-paste FFmpeg command without memorizing codec flags.
- Check a WMA file's sample rate and duration before encoding to OGG.
