FLAC vs WAV: is one better quality?

Let's settle the big one first: they sound identical. Both FLAC and WAV are lossless, so there's no quality difference to hear. The real decision is about size, tags and which tools you're using.

Quality: a tie

WAV stores raw, uncompressed PCM audio. FLAC compresses that losslessly — it packs the same samples into a smaller file and reconstructs them bit-for-bit on playback. Decode a FLAC and you get back exactly what went in. So anyone claiming one "sounds better" than the other is mistaken: at the same source, the audio is identical.

File size

This is FLAC's big win: it's typically 30–60% smaller than the same audio as WAV, with zero quality cost. For a music library of any size, that's a lot of space saved — the main reason FLAC is the standard for archiving and lossless streaming.

Metadata & tags

FLAC has first-class support for metadata — title, artist, album, track number, embedded cover art — so your library stays organised and looks right in any music player. WAV's tagging support is minimal and inconsistent across software, so WAV files often show up as untitled. If you're building a collection, FLAC's tags matter.

Compatibility

WAV is the more universal container — it's the safe input for virtually every DAW, audio editor, sampler, CD-burning tool and older/hardware player. FLAC support is excellent in modern music players and increasingly in hardware, but some pro-audio and legacy tools still expect WAV. For editing and production, WAV is the frictionless choice; for storage and listening, FLAC.

When to use which

• Use FLAC for: archiving a music library, lossless downloads/streaming, anywhere size and tags matter.
• Use WAV for: editing in a DAW, mastering, CD burning, or feeding older/pro hardware that expects PCM.

Convert either way

Processed privately, auto-deleted after an hour:

• Convert WAV to FLAC — shrink for your library (lossless).
• Convert FLAC to WAV — uncompressed PCM for editing.

Need a small, shareable file instead of lossless? FLAC to MP3.

TL;DR

Same quality, different trade-offs. FLAC for storage — smaller, with proper tags. WAV for editing — universal, uncompressed. Neither sounds better than the other.
