WMA (.wma) · Max 20 MB
WMA files are already compressed, but MP3 can compress further at a different bitrate. The size reduction is significant for sharing, uploading, and storage.
For email attachments, 128-192kbps works well. For music sharing, use 256-320kbps. AudioUtils lets you drop your file and convert instantly. No upload to a server, no waiting.
Both WMA and MP3 are lossy formats. Each re-encode can degrade quality slightly. Convert once and keep the result. Choose the right bitrate for your use case. Higher bitrate means better quality but larger files.
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.
