How to add a stamp to a PDF

Save your stamp once, drag it onto the page, export. Four steps, in the browser or on your Mac, with no printer and no scanner.

Step 1 — Get an image of your stamp

Any photo or PNG of the stamp works: your company stamp, a notary or approval stamp, your signature. Press one clean impression on white paper and photograph it, or choose No — use my phone in the app and take the photo with your phone. The paper is cut away as the image is read, so the stamp sits on the PDF as ink rather than as a white box. Need a PAID stamp for invoices? Download one of the free PAID stamp templates.

Step 2 — Add it at its real size

Open the web app, click Add… in the stamps panel, choose Yes — upload and pick the image. Type the stamp's Real size on paper and click Save stamp. It stays in your stamps panel for every PDF after this one.

Step 3 — Put the stamp on the PDF

Open the PDF and drag the stamp onto the page. It lands at its real printed size on A4, Letter or any other page. Move it, turn it by the handle above it, or resize it. To insert the same stamp on every page, select it and click Apply to next pages.

Step 4 — Export the stamped PDF

Click Save As…. You get a new PDF with the stamp drawn into the page, and the original file stays as it was.
