Convert WAV to FLAC Online

The ultimate archival tool. Compress your WAV master files to FLAC without losing a single bit of audio data.

1

Upload WAV

Select .wav files from your device. Supports 16-bit and 24-bit audio.

2

Set Compression

Choose Level 5 (Balanced) or Level 8 (Maximum compression).

3

Download FLAC

Get your smaller, identical audio file instantly.

Why Audiophiles Love FLAC

FLAC reduces file sizes by roughly 40-50% compared to uncompressed WAV, but when it plays back, it is mathematically identical to the source. It's the standard for high-res audio storage.

Efficiency First

Why Switch to FLAC?

Save hard drive space, keep your metadata organized, and never compromise on quality.

100% Lossless

Unlike MP3 or AAC, FLAC keeps every single frequency peak and valley of your recording.

Rich Metadata

Store cover art, lyrics, and custom tags directly in the file, something WAV struggles with.

Half the Size

Compress your audio library to nearly half its size without checking a single bit.

Adjustable Levels

Customize compression from Level 0 (fast) to Level 8 (maximum space saving).

Pure Lossless Math.
Smaller Files. Same Data.

Converting WAV to FLAC is different from most conversions. It is not an approximation; it is a mathematical repackaging. Think of it like zipping a text file—the content remains identical, but the container shrinks.

Our engineering team implemented FFmpeg's robust libFLAC encoder with strict checksum validation. When you upload a WAV file, we calculate its audio fingerprint. After converting to FLAC, the decoder ensures the fingerprint matches exactly.

This means you get a file that is 30-50% smaller than your original WAV, yet bit-for-bit identical when played back. It is the ultimate archival format.

LibFLAC Verified

Space Saver

Reduces file size by up to 50% without quality loss.

Checksums

Built-in error checking ensures file integrity.

Metadata Support

FLAC supports rich tagging (cover art, artist, lyrics).

Understanding Lossless Compression

FLAC (Free Lossless Audio Codec) works similarly to a Zip file, but it is specifically optimized for audio data. While general-purpose compression tools might shrink an audio file by 10-20%, FLAC can achieve 30-60% reduction.

Crucially, when a FLAC file is played back, it is decoded into PCM data that is identical to the original WAV. There is absolutely no generation loss. This makes FLAC superior to MP3, AAC, or OGG for archiving, editing, and high-fidelity listening.

WAV files are uncompressed PCM audio. They are huge and cumbersome. Converting them to FLAC is "free lunch"—you get the same quality in a package that is half the size.

Audio Glossary

PCM

Pulse Code Modulation. The raw digital representation of analog audio, as found in WAV files.

Lossless

Compression that allows the original data to be perfectly reconstructed from the compressed data.

Checksum

A mathematical value used to verify that a file has not been corrupted or altered.

Bit Depth

The number of bits of information in each sample (e.g., 16-bit CD quality, 24-bit studio quality).

Vorbis Comment

The metadata tag format used by FLAC (and OGG) to store artist, title, and other info.

Transcoding

Converting from one encoding to another. Lossless to Lossless transcoding is safe from quality loss.

Conversion Tips

Archiving

If you are ripping CDs, always use FLAC instead of WAV. You save 50% space and can tag the tracks properly.

Compression Levels

Don't worry too much about Level 5 vs Level 8. The size difference is usually small. Level 5 is fine for most uses.

Safe Conversion

Converting WAV to FLAC is completely reversible. You can always convert FLAC back to identical WAV later.
