when SCP, does file content change?

Good day to you all,

Just want to check here, i know when scping a file, size might change due to space issue. it might sound silly, but does file content get change too? if so, what kind of situation that might be?

scp doesn't change the content, no. ftp might, suddenly deciding to be all "helpful" and translate all cr into cr-lf in a binary file, but scp won't.
