WAV to FLAC Converter

1. Upload your WAV file (up to 50 MB).
2. Click 'Convert WAV to FLAC' — takes 5-15 seconds.
3. Download the FLAC file.

WAV to FLAC is a truly lossless conversion — FLAC is usually 50% smaller than WAV with zero quality loss. Perfect for archiving a WAV library without losing any audio data.

WAV is uncompressed — files are large. FLAC is also lossless, but with ~50% compression. Converting WAV to FLAC is a truly lossless operation — every audio sample is preserved exactly, but the file is half the size. This is the standard way to archive audio for long-term storage without any quality loss.

The converter decodes the WAV (PCM) audio and re-encodes it as FLAC using lossless compression. Every sample is preserved exactly — the FLAC decompresses to byte-identical PCM. File size drops by ~50% with zero quality loss.

• Archiving WAV recordings without quality loss.
• Reducing storage for a WAV-heavy library.
• Preparing WAV files for long-term archival.
• Converting production exports to compressed lossless.
• Standardizing an audio library to FLAC.
• Saving disk space while keeping lossless quality.
• Converting Hi-Res WAV for portable playback (with FLAC support).

WAV → FLAC is lossless — every sample is preserved exactly. The FLAC file decompresses to byte-identical PCM, so audio quality is literally identical to the original WAV. Only the storage format differs.

• Only ~50% size reduction (WAV is already uncompressed).
• For more compression, use MP3 (lossy) or AAC.
• Not all players support FLAC (though most modern ones do).
• FLAC files are still larger than MP3.
• For streaming, MP3 is more compatible.

• Output FLAC plays on most modern devices and software.
• Works with VLC, Foobar2000, iTunes (with plugin), phones (some).
• Metadata (Vorbis comments) preserved.
• Accepted by most audio software and platforms.
• Standard FLAC — no special software needed for supported devices.

• WAV → FLAC is truly lossless — no quality loss at all.
• FLAC files are ~50% smaller than WAV.
• Hi-Res WAV (>48 kHz) is preserved exactly.
• For portable playback, FLAC is more compatible than WAV on some devices.
• For maximum compression, convert to MP3 (lossy).

FLAC file is only 50% smaller

FLAC is lossless — it can't achieve the 90% reduction of MP3. For more compression, use MP3.

FLAC doesn't play on my old device

Some older devices only support MP3/WAV. For those, use WAV or convert to MP3.

Conversion takes longer than expected

Lossless compression requires more CPU than lossy. Expect 5-15 seconds per file.
