Drop WMA files onto the converter, paste them, or click to choose. You can add many at once.
OGG is already selected. If you like, adjust the quality, sample rate or channels before or after adding files.
Each file is converted in your browser in seconds. Save them one by one, or all at once as a ZIP.
Windows Media Audio
Microsoft's legacy audio format
WMA (Windows Media Audio) comes from the Windows Media Player era. Many older music libraries and Windows recordings still use it.
Ogg Vorbis
The open alternative to MP3
OGG files usually contain Vorbis audio, a free and patent-free lossy codec. It is common in video games, on Android and in open-source software.
Audio is converted by ffmpeg running inside your browser. Your files never reach a server.
Queue up to 50 files and download them one by one or together as a ZIP.
Set the bitrate, bit depth, sample rate and channels — or simply keep the sensible defaults.
Add your WMA files to the converter above. OGG is already selected as the output, so conversion starts right away. When a file is ready, click Download, or use Download all to get a ZIP.
Both formats are lossy, so re-encoding adds a little loss. Choose a bitrate equal to or higher than the original (for example 192–256 kbps) and the difference will be inaudible.
160–192 kbps sounds transparent for most music, and 96–128 kbps is fine for speech. Vorbis handles low bitrates better than MP3.
No. The WMA to OGG conversion runs entirely in your browser using ffmpeg compiled to WebAssembly. Your files are never sent to a server, so even private recordings stay on your device.
Yes. Add up to 50 files; they are converted one after another, and you can download each OGG file separately or all of them together as a ZIP archive.
