Why WMA Conversion Requires a Desktop Tool
WMA (Windows Media Audio) is a proprietary Microsoft codec. Encoding WMA audio requires licensed native libraries that browsers cannot access through standard Web APIs. This tool lets you inspect your AAC or M4A file metadata and preview playback, then follow the platform guide below to convert using a free desktop application.
