Why convert WMA to MP3?
WMA is an old Windows Media audio format that iPhones, Android phones, Macs and many car stereos cannot play. Converting WMA to MP3 makes old music collections and recordings playable everywhere.
When to keep the WMA
There is little reason to keep WMA once you have MP3s, unless an old Windows program or device needs the WMA files.
Tips for the best result
- The MP3 uses high-quality variable bitrate encoding.
- Song details such as title, artist and album are usually carried over to the new file.
- Convert a whole album at once and download it as a ZIP.
Common problems and fixes
- The file will not convert.
- WMA files bought from old online music stores may have DRM protection, which prevents conversion.
- The MP3 sounds no better.
- Converting keeps the quality of the original; it cannot restore what the WMA encoder removed.

How do I convert WMA to MP3?
Click Select File or drop your WMA file onto the upload box. The converted MP3 appears in the list below with a download button. You can add many files at once and download them together as a ZIP.
Is it really free?
Yes. There is no sign-up and no watermark. To keep the service available for everyone there is a 95MB limit per file and a cap on how many files one connection can process in a short period.
Are my files stored?
Your upload is used only to make the converted file. Images are processed in memory; other files are written to a private temporary folder that is deleted as soon as the conversion finishes. Nothing is kept after the result has been sent back.
Will quality drop?
For images, a little, by design: the image is re-encoded at the Quality you choose (default 75%). Audio and video are re-encoded with high-quality settings; documents keep their text and layout as far as the target format allows. Converting never restores detail that is already missing from the original.
How this works: your file is uploaded over HTTPS and converted on this server with open-source engines (libvips for images, FFmpeg for audio and video, LibreOffice and Pandoc for documents, Calibre for ebooks, Ghostscript and Inkscape for PDF and vector files). Images are processed in memory; other files use a private temporary folder that is deleted as soon as the conversion finishes.
