Add an official stamp to a PDF online
Add an official stamp to a PDF online without any software: design your stamp or company seal, download the transparent PNG or the SVG, and place it on the page in whatever PDF editor you already use. Each download can take a locked serial number, and the date and time can fill themselves in.

How to make PDF Stamp

Frequently asked questions
Is the pdf stamp free?
Designing and previewing a pdf stamp is free, with no account and no watermark on the preview. Downloading the file costs $1.50 for one format or $4 for every format in a single zip, paid once. There is no subscription to cancel.
Can I add a date to the pdf stamp?
Yes. Toggle the date on and it's placed inside the stamp; you can also add a serial number, change the color, or add your logo.
What format do I get?
A transparent PNG to drop onto any document, a white-background PNG, a JPG, an SVG vector, a print-ready PDF, and a Word file that keeps the date, time and serial as text you can retype. Or all of them at once in a single zip.
How do I add an official stamp to a PDF?
Design the stamp here, download the transparent PNG or the SVG, then place it on the page in whichever PDF editor you use. The transparent background means it sits over the text rather than covering it with a white box.
