Stamp PDF Pages Online
Mark documents with a bold red seal — APPROVED, PAID, FINAL, RECEIVED, or any word you choose — placed neatly in the top-right corner of every page, just like a rubber stamp on paper. The semi-transparent bordered design stands out without hiding the content underneath. Everything is stamped locally in your browser, so invoices, HR files, and other confidential documents are never transmitted to a third party.

Frequently asked questions
Where does the stamp appear?
The stamp is drawn as a red bordered label in the top-right corner of every page, with semi-transparent styling so underlying content stays readable.
Can I use lowercase or multi-word stamps?
Yes, any text works. Short uppercase words like FINAL or COPY look most like a traditional rubber stamp, but the choice is yours.
Is the stamp permanent?
The stamp is drawn into the page content of the downloaded file, so it displays in every PDF viewer and survives printing like any other content.
