WAV (Waveform Audio File Format) uses uncompressed lossless encoding and is best for professional audio editing, mastering, and archival in DAWs and production software. WMA (Windows Media Audio) uses lossy compressed encoding and excels at Windows-based media libraries, legacy devices, and corporate audio systems. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Legacy Windows libraries that accept nothing else — modern cases should stay WAV or FLAC.
