Converting FLAC to MP3 is a common task when you need plays everywhere. FLAC (Free Lossless Audio Codec) compresses audio with zero quality loss — typically to about half the size of WAV. It is the audiophile favourite for archiving and high-fidelity listening, at the cost of larger files than lossy formats. MP3, on the other hand, gives you plays everywhere and small files. ZeroUpload performs this conversion entirely inside your browser, so your FLAC file is never uploaded to a server.
