How can I prevent file size from ballooning when using linked images?

Why are there significant differences in file sizes despite the same format and approximate pixel counts?

So PNG uses compression, and put simply, the best-case is where all bytes are identical and worst-case is going to be random data. My very basic understanding of PNG is that it compresses based on "...
