About FLAC and WAV
FLAC is lossless compression for audio — bit-identical to the source at roughly half the size of WAV. It is the archival format of choice for music collections and masters.
WAV is uncompressed PCM audio — the raw samples with a small header. It is the standard interchange format for recording, sampling and production work, at the cost of roughly 10 MB per minute of stereo.
Converting FLAC to WAV is lossless in both directions — the audio comes through bit-perfect, so files can move back and forth without generational loss.
How the conversion works
This tool runs FFmpeg — the same engine behind most media software — compiled to WebAssembly, entirely in the browser. The file is read locally, converted locally and saved straight from memory; nothing is ever uploaded, which also means no queues and no server-side file size limits.
The converter itself is a one-time ~31 MB download on the first conversion, cached by the browser afterwards. Once it is loaded, everything works offline.
