WMA (Windows Media Audio) uses lossy compressed encoding and is best for Windows-based media libraries, legacy devices, and corporate audio systems. FLAC (Free Lossless Audio Codec) uses losslessly compressed encoding and excels at high-fidelity music archives and audiophile listening where quality matters more than file size. 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.

No — FLAC holds the WMA fidelity exactly, artifacts included. It prevents further loss; it cannot reverse past loss.
