Lossless preserved

FLAC to WAV is a lossless operation — you get the same audio data with no compression artifacts.

FLAC: lossless audio explained

FLAC (Free Lossless Audio Codec) is the audio equivalent of a ZIP file for music. It compresses audio by 40–60% compared to WAV, but decompresses to bit-perfect output — the exact same audio signal as the source, with no samples altered or removed. Unlike MP3 or AAC, FLAC's compression introduces zero artifacts.

The main reasons to use FLAC: archiving master recordings (never lose quality when you need to re-encode later), audiophile listening (on equipment transparent enough to reveal MP3 artifacts), and music collection management (store once in lossless, transcode to any lossy format on demand).

Common conversions: FLAC to MP3 when you need to sync music to a device with limited storage or that doesn't support FLAC. FLAC to WAV when your audio editing software requires uncompressed input. MP3 to FLACre-wraps the audio in a lossless container — it won't recover lost quality, but it's useful for organizing a collection in a uniform container format.

Common questions

Is FLAC truly lossless?
Yes. FLAC (Free Lossless Audio Codec) compresses audio like a ZIP file — the original waveform is bit-perfect after decompression. A FLAC file is mathematically identical to the original WAV. It's typically 40–60% smaller than WAV while preserving every sample.
Can I tell the difference between FLAC and MP3?
In blind listening tests, most people cannot distinguish FLAC from MP3 at 192 kbps or higher on typical speakers and headphones. The practical case for FLAC is archiving — if you're storing a master copy of music, FLAC ensures you can always derive any lossy format without quality degradation.
Why can't I play FLAC on iTunes or my iPhone?
Apple uses ALAC (Apple Lossless Audio Codec) as its lossless format. FLAC is not natively supported in iTunes or older iOS versions, though modern iPhones running iOS 11+ can play FLAC through the Files app. For iTunes, convert FLAC to ALAC (M4A) or MP3 for compatibility.
Does FLAC to MP3 lose quality?
Yes — MP3 is a lossy format, so converting FLAC to MP3 applies compression. However, FLAC to MP3 at 192 kbps or higher is perceptually transparent: the resulting MP3 sounds identical to the FLAC source on normal listening equipment. The quality loss is in the encoding, not from starting with FLAC.
