Convert FLAC to MP3

The classic library conversion: FLAC is lossless and large, MP3 is lossy and small enough to carry around. Because the source is a perfect copy, this is the best-case version of MP3 encoding - one generation of loss, from an untouched original.

What is FLAC?

Lossless compression for audio: about half the size of a WAV, with every sample bit-for-bit intact. It's what people archive CDs into and what hi-res download stores sell. If a conversion starts from FLAC, it's starting from a perfect copy.

What is MP3?

The format that made digital music portable, and thirty years on it's still the safest bet that a file will simply play - any device, any car, any decade-old bit of hardware. It's lossy, its patents expired in 2017, and no browser has ever been able to write one, which is why encoding it here needs LAME.
