PDFs they can read but not change.

You’ve sent the contract. The recipient opens it, reads it — and then deletes a page. Not what you wanted.

With pdfMachine you decide exactly what they can do once it’s open.

Read but not change. They can view every page, but they can't change the content. No edits.
Read but not print. On-screen only. Useful for things you’d rather not see on a noticeboard.
Read but not copy. Block text and graphics from being extracted. Your wording stays in your PDF.
Read but not rearrange. Pages stay in the order you sent them. No splitting, no extracting, no reshuffling.

Send the view. Guard the content.

View only. Edit never.
