WMA (.wma) · Max 20 MB
Traditional online converters upload your file, process it on a remote server, and send it back. That's slow, insecure, and wasteful. AudioUtils eliminates the upload entirely.
The converter uses WebAssembly to run a compiled audio engine in your browser tab. It reads your file locally, converts it locally, and saves the result locally. The network is never involved.
This matters for sensitive audio. Unreleased music, legal recordings, private conversations. With AudioUtils, your files stay yours. Both WMA and MP3 are lossy formats. Each re-encode can degrade quality slightly. Convert once and keep the result.
Frequently Asked Questions
Why can't I play WMA files on my Mac?
macOS doesn't natively support WMA. Converting to MP3 makes your files playable on Mac, iPhone, and all Apple devices.
Is WMA better than MP3?
At lower bitrates, WMA can sound slightly better. At higher bitrates, the difference is negligible. MP3 wins on compatibility by a wide margin.
What about WMA Lossless files?
WMA Lossless files will be converted to MP3 with lossy compression. If you want to preserve lossless quality, convert to FLAC or WAV instead.
Can I convert DRM-protected WMA?
No. WMA files with DRM (Digital Rights Management) protection cannot be converted by third-party tools.
