Compression is lossy.
So when you zip some files and then unzip them, some of the bytes are missing? Really?!
It's only the zeros, so you're not really missing anything.
If nothing is lost, what did you compress away? Decompression is magic, I ain't gotta explain shit
If you want the magic explained, here's a start: https://en.wikipedia.org/wiki/Lempel%E2%80%93Ziv%E2%80%93Welch
Newer fractional arithmetic encoding can get crazy

you compressed away redundant data, 1111111000000000011111111 -> (1x7)(0x10)(1x8)
Keep your magic ways to yourself, wizard
