PDFs, uploaded images, signatures and added text are processed locally for this editing session. They are not uploaded for PDF processing or saved to your account. Download your work before leaving; the session is not a saved document library.

The site still makes ordinary requests to load the application. Read our privacy policy for details.

Before you start

Is PDF stamping free?

Yes. Adding your own images, signatures and text, then downloading the PDF is free and does not require an account. Creating a stamp in the stamp maker is also free; downloading that design as a PNG requires paid access. See PNG download pricing.

Can I create a stamp to use here?

Start with a stamp template or a blank design in the stamp maker. Download the PNG with paid access, then upload it here using Stamp. You can also use a PNG or JPEG you already have.

Does this create a digital signature?

No. Drawn signatures and stamp images are visual marks, not cryptographic digital signatures. This tool does not verify signatures. Editing a digitally signed PDF may invalidate its existing signatures.

Which PDF edits are supported?

You can add images, signatures and new text over PDF pages. You cannot rewrite the original PDF text or redact content. Password-protected and encrypted PDFs are not supported.
