Preserve Perfect Audio Quality at Half the File Size
WAV is uncompressed and lossless, but it wastes space by storing raw PCM data without any compression. FLAC uses mathematical compression (like a ZIP file for audio) to shrink files by 40-60% while preserving every single sample bit-for-bit. It is the gold standard for archiving music collections, studio recordings, and vinyl rips.
Why Convert WAV to FLAC?
Reclaim 40-60% of storage space with zero audio quality loss — a 50 MB WAV album becomes a 25 MB FLAC album with identical sound.
FLAC supports rich metadata (Vorbis comments) including album art, lyrics, and ReplayGain tags — WAV metadata is extremely limited.
Music archivists and audiophile communities standardize on FLAC — it is the accepted format for lossless sharing, trading, and archiving.
Streaming services like Tidal, Deezer HiFi, and Amazon Music HD use FLAC for their lossless tiers, making it the professional standard.

How to Convert WAV to FLAC
Upload your WAV masters
Add the uncompressed WAV files from your recording sessions, CD rips, or vinyl digitizations. All sample rates and bit depths are supported.
Lossless compression
FLAC encoding compresses the PCM data mathematically — like zipping a file. When decoded, you get the exact same audio data back, bit for bit.
Download compact lossless files
Your FLAC files are ready. They are typically 40-60% smaller than the WAV originals with absolutely no quality compromise.
Frequently Asked Questions
Is FLAC truly lossless — will I get back the exact same audio if I convert FLAC back to WAV?
expand_more
Yes, absolutely. FLAC-to-WAV produces a bit-identical copy of the original WAV. You can verify this by comparing MD5 checksums of the audio data. This is guaranteed by the FLAC specification.
Why not just use ZIP to compress WAV files?
expand_more
ZIP compresses WAV files by about 10-20% because generic compression algorithms cannot exploit audio-specific patterns. FLAC achieves 40-60% reduction because it understands the structure of audio data and compresses accordingly, while remaining directly playable without extraction.
Can I add album art and track info to FLAC files?
expand_more
Yes. FLAC uses Vorbis comments for metadata, which support artist, album, title, genre, track number, embedded album art, lyrics, and custom tags. This is a major advantage over WAV, which has minimal metadata support.
Do Apple devices play FLAC natively?
expand_more
iPhone and iPad support FLAC playback since iOS 11. macOS has supported FLAC in Apple Music since Catalina. However, iTunes on older systems does not — you would need ALAC (Apple Lossless) for those.
What FLAC compression level should I use?
expand_more
All FLAC compression levels (0-8) produce identical audio quality. Higher levels just compress the file slightly more at the cost of encoding speed. Level 5 (the default) offers the best balance. The difference between level 0 and level 8 is typically only 5-10% in file size.
Pro Tips for WAV to FLAC Conversion
Use FLAC compression level 5 (default) for the best balance of file size and encoding speed — going higher saves minimal space.
Add proper metadata tags after converting — FLAC Vorbis comments are far richer than WAV RIFF tags.
For vinyl digitizations, keep the original WAV alongside FLAC as a safety net until you verify the FLAC MD5 checksums.
If sending to someone on Apple, check their iOS version — FLAC playback requires iOS 11 or later.
