Converting FLAC to M4A is a common task when you need better quality than mp3 per byte. 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. M4A, on the other hand, gives you better quality than mp3 per byte and efficient compression. ZeroUpload performs this conversion entirely inside your browser, so your FLAC file is never uploaded to a server.
