ELI5:
When you make a collage of letters and words and images on a page of paper with some items on top of others, there can be a lot of messy mistakes and cuts and pieces of tape hanging out.
If you put the collage on a photocopier, you get a nice clean picture of the collage, no folds or creases or tears or tape sticking out.
Slightly more complex, but slightly more accurate, because I don’t think OP is actually 5:
“Recompressing” a PDF is similar – it can discard items that are duplicated or not used anymore. It can also use other compression methods to reduce the size of an image inside a PDF, or lossless compression methods to squeeze the size of text.
