Frequently asked questions
How to stamp a PDF for free?
Upload the PDF, choose text or stamp, place it where you want, and download the stamped document. Stamping PDFs is free, no registration, and 100% in the browser.
Can I add stamps like "Confidential" or "Approved" to the PDF?
Yes. You apply text stamps like Confidential, Approved, or Draft at any position. Nothing is sent to a server — the stamp is applied locally in your browser.
Is stamping PDF online safe?
It's safe: the file stays on your computer because the stamp is applied in the browser itself. You can stamp confidential documents for free, without registration, and without uploading anything.
