M4R vs FLAC
FLAC is lossless, but it can't restore detail already removed by M4R's compression — the file just gets bigger. Convert when an app or editor requires FLAC.

About M4R and FLAC
M4R: M4R is the iPhone ringtone format. It is an AAC audio file (the same as M4A) with a different extension, and iOS only accepts ringtones up to 30–40 seconds long.
FLAC: FLAC is an open lossless format that shrinks audio to 50–60% of WAV size without losing any quality. It is the favourite format of audiophiles and hi-res music stores.
