Convert WMV to FLAC — Free Online Converter

WMV's ASF container holds audio encoded as WMA — either WMA Standard (lossy, up to 320 kbps), WMA Pro (multichannel lossy), or WMA Lossless (bit-perfect). FLAC (Free Lossless Audio Codec) is the open-source lossless audio standard, achieving 50–70% compression of PCM data with guaranteed bit-perfect reconstruction. Converting WMV to FLAC extracts the audio from Microsoft's proprietary ecosystem and stores it in the universally supported, patent-free FLAC format — ideal for archival, audiophile collections, and cross-platform lossless audio.

WMA audio is locked into the Microsoft ecosystem — many Linux players, macOS, and web browsers cannot decode it natively. FLAC is the universal lossless audio format: supported on Linux (native), Android (native since 3.1), Windows (via codec pack), macOS (VLC, foobar2000), and most high-fidelity audio equipment. If your WMV contains WMA Lossless audio, converting to FLAC preserves every bit of quality in a format the entire world can play.
