Place a text stamp (DRAFT, APPROVED, PAID…) anywhere on your pages.
Stamp a PDF with custom text in any of nine positions — control the size, opacity, rotation and colour. Unlike a watermark that repeats across the page, a stamp is a single mark, perfect for status labels and sign-offs. Files are processed securely and never stored.

A stamp is a distinct mark placed at a specific spot — PAID in the corner of an invoice, APPROVED beside a signature block. A watermark is large, faint and spread across the page to mark the whole document. Stamps state a status; watermarks assert ownership or restriction.
Yes — drag the stamp to any position on the page preview rather than picking from fixed corners, and adjust size, colour, opacity and rotation. That matters because the right spot is usually document-specific: next to a total, over a signature line, or clear of existing text.
The stamp is placed in the same position across pages, which suits status marks that should appear throughout. For a single-page stamp, extract that page, stamp it, then merge it back — a little more work, but it keeps the rest of the document untouched.
Yes, Add Stamp to PDF is completely free. No signup, no account, and no watermark on outputs. A Pro tier is available for 100 AI ops/day and larger file sizes.
Add Stamp to PDF uploads your file over an encrypted connection to our own processing server, converts it, and returns the result. The file is deleted immediately after processing and is never used for anything else. It is not sent to any third party, and we keep no copies.

Drag your stamp anywhere on the page
Drag or snap: Position the stamp precisely by dragging it on the page, or tap one of the nine grid spots for an instant corner/edge/centre placement. Either way it lands on every page at the same spot.
Full control: Any colour, size, opacity and rotation (0–360° — try 45° for a diagonal DRAFT). The stamp is always kept fully on the page. Latin, Arabic and Thai text are supported.
Privacy: Your PDF is sent over an encrypted connection, stamped in memory, and deleted immediately after — never stored.
