What is WAV?

Uncompressed audio format. Perfect quality with no data loss. Standard for music production and professional audio work.

What is FLAC?

Lossless compression. Perfect quality at roughly half the size of WAV. The choice for audiophiles and archiving.

Why Convert WAV to FLAC?

WAV and FLAC contain identical audio — both are lossless. The only difference is compression. WAV is uncompressed PCM; FLAC applies a lossless algorithm that reduces file size by 50–60% without touching a single bit of audio data. A 50 MB WAV becomes roughly 25–30 MB as FLAC, and you can convert back to WAV and get a bit-identical file. This makes FLAC the obvious choice for archiving and storage. A music collection of 500 WAV albums might be 250 GB. The same collection in FLAC fits in under 100 GB with zero quality compromise. FLAC is also universally supported by serious audio software — iTunes added native FLAC support in 2017, every Linux media player handles it, and Roon, Plex, Naim, and Tidal masters all use FLAC as the reference lossless format. The only scenario where WAV beats FLAC is maximum compatibility with very old or basic hardware — some 2005-era CD players and car stereos can read WAV from USB but not FLAC. For anything modern, FLAC is strictly better than WAV for storage and archiving.

Who Uses This Converter

Music library archiving

Replace WAV with FLAC to cut your music library size in half without any quality loss. Keep FLAC as your master format and convert to MP3 for devices.

Streaming & Tidal upload

Tidal accepts FLAC for Masters-quality uploads. Convert your WAV masters to FLAC before submission.

Backup & cloud storage

Storing a large WAV collection on cloud storage is expensive. FLAC cuts the size in half, halving your storage bill with zero audio compromise.

Sharing lossless audio

FLAC is the standard for sharing lossless audio online — music forums, Bandcamp, and audiophile communities all use FLAC. Convert WAV before sharing.

Frequently Asked Questions

Is WAV to FLAC truly lossless?

Yes, 100%. FLAC compression is mathematically lossless. You can convert WAV to FLAC and back to WAV and get a bit-identical file. No audio data is lost.

How much space does FLAC save over WAV?

Typically 40-60%. A 50MB WAV file becomes roughly 25-30MB as FLAC. The exact ratio depends on the audio content — simpler sounds compress better.

Can all devices play FLAC?

Most modern devices support FLAC. Android has native support. iPhone added FLAC support in iOS 11. Windows supports it natively in Windows 10+. Older devices may need MP3 or AAC instead.

Should I keep my WAV originals after converting to FLAC?

Not necessary. FLAC is lossless — you can always convert back to WAV with identical quality. Many professionals archive exclusively in FLAC to save storage.

How much smaller will the FLAC be?

Typically 40–60% smaller than the source WAV. A 50 MB WAV becomes 20–30 MB FLAC. Compression ratio varies by content: sparse recordings (voice, acoustic guitar) compress more than dense material (orchestral, electronic). The audio is bit-identical regardless of compression ratio.

Can I use FLAC files on iPhone and iTunes?

Yes. Apple Music and iTunes on macOS and iOS have supported FLAC natively since 2017. On iPhone, import FLAC files via the Files app or through Finder. Older iPhones running iOS 10 or earlier don't support FLAC natively — use ALAC (Apple Lossless) instead.
