FLAC vs WAV

No. Both formats are lossless and store the exact same audio data. A FLAC file converted from WAV and back again is bit-for-bit identical to the original. The only difference is file size — FLAC uses compression to store the same data more efficiently.

FLAC is the better choice for most people. It produces files 40–60% smaller than WAV with zero quality loss, excellent metadata support for album art and tags, and wide compatibility. WAV is only preferable if you need maximum compatibility with older audio software.

Yes, absolutely. Since both formats are lossless, converting WAV to FLAC is completely lossless. The resulting FLAC file contains exactly the same audio data as the original WAV, just in a more compact form.

WAV is a simpler format with zero decoding overhead, making it easier for Digital Audio Workstations to process in real time. Most professional audio software supports WAV natively out of the box, while FLAC support can vary.

Yes — FLAC has excellent metadata support via the Vorbis Comment standard, handling artist, album, track title, year, genre, and embedded album art. WAV metadata support is inconsistent across software, making FLAC far better for music library management.
