Add Page Numbers and Watermarks Before You Send
Stamp page numbers and a CONFIDENTIAL/DRAFT watermark locally, then password-protect when access control matters.
A merged proposal looks unfinished without page numbers. A draft that escapes into the wild without a watermark invites confusion.
Page numbers
Open /tool/pdf-page-numbers after the packet order is final. Numbering before you delete pages means you’ll renumber anyway.
Watermarks
/tool/pdf-text-watermark puts a diagonal DRAFT or CONFIDENTIAL stamp across pages. It’s a visible deterrent, not encryption.
Then lock if needed
Follow with /tool/protect-pdf when only named people should open the file. Typical order: merge → edit → numbers/watermark → compress → protect.
Placement and contrast
Put page numbers after the page order is final. Inserting or deleting a sheet later shifts every number, and a packet that says page 4 of 9 when it has 10 pages looks careless. Start numbering at 1 unless the client asked for a cover that stays unnumbered. A watermark should be readable as a stamp and still leave the body text readable. Huge opaque letters across a contract are worse than no stamp. DRAFT is for files that will change. CONFIDENTIAL is for files that should not be casually forwarded — it does not stop a screenshot. If you need both a stamp and a password, stamp first, then lock. You cannot edit the stamp on a file you have already password-protected without unlocking it. Preview one page at 100 percent before you send the packet. If the stamp covers a signature line or a total, move it or shrink it and export again. Page numbers in the footer should not collide with a footer that was already in the source PDF. When they do, the packet looks like two captions stacked. Fix that before you compress or lock the file, because those later steps are harder to undo.
