Converting OGG to FLAC is a common task when you need lossless quality. OGG (Vorbis) is a free, open compressed audio format that often beats MP3 in quality at the same size. It is popular in gaming and open-source software, though desktop support is less universal than MP3. FLAC, on the other hand, gives you lossless quality and smaller than wav. ZeroUpload performs this conversion entirely inside your browser, so your OGG file is never uploaded to a server.
