FLAC converter

FLAC is where music collections and masters live; MP3 and WAV are where they need to go for devices and editors. These conversions run ffmpeg compiled to WebAssembly inside your browser, so your library stays on your machine.

What is FLAC?

FLAC (Free Lossless Audio Codec) compresses audio to roughly half of WAV size while keeping every sample bit-perfect, which made it the archival and audiophile standard. It is open and royalty-free, plays in browsers and most modern software, but car stereos, older devices and plenty of apps still want MP3, and audio editors often prefer plain WAV input.
