Does this remove links as well?

Yes. Links are annotations, so they go too. That is worth knowing before running it on a document with a contents page.

Does it change the page content?

No. Only the annotation layer is removed.

What about form fields?

They survive. Use Flatten if you want the answers fixed into the page.

Strip comments, highlights and sticky notes before sharing a document.

How it works

Review comments have a way of surviving into final documents, where they are visible to anyone who opens the file and occasionally embarrassing. This removes them. It also removes links, because in PDF terms a link is an annotation too — so a clickable contents page will stop being clickable.
