Why use this converter
100% private
Your OGG files convert entirely in your browser - nothing is ever uploaded to a server.
Batch conversion

Won't add extra loss
FLAC is lossless, so this conversion won't degrade quality further - though it can't restore detail already lost when the source was encoded as OGG.
No file size limits
Since nothing uploads to a server, there's no artificial cap on how large a file you can convert.
