Frequently Asked Questions

Which stamp texts are available?

DRAFT, CONFIDENTIAL, and other common markings — applied diagonally across every page.

Can I stamp selected pages only?

Stamping covers every page; extract the pages you need first, then stamp the subset.

Does stamping work on scanned PDFs?

Yes — the stamp overlays the page image, so scans work exactly like digital pages.

Is my stamped PDF uploaded anywhere when using PDF Stamp?

No — stamping runs locally in your browser, free with no signup.
