What compression does to FLAC
Re-compresses at FLAC's maximum compression level; the audio stays bit-identical.
It's lossless, so there are no quality levels to choose between: every file comes back with identical contents, just packed more tightly.
Need it much smaller? A high-bitrate MP3 is well under half the size of the FLAC and sounds the same to most listeners. Convert FLAC to MP3
Why there are no target sizes
Lossless compression never throws anything away, so how small a FLAC can get depends entirely on what's in it. There's no quality dial to turn until the file hits 1 MB or 100 KB, which is why FLAC has no target-size pages.
If you need a specific size, convert to a lossy format first, for example FLAC to MP3.
