Why Add a Stamp, Signature or Text to a PDF?
Printing, signing or stamping by hand and re-scanning a document wastes time and lowers quality. Adding a stamp or signature digitally keeps the file crisp and is far faster.
Businesses add a company stamp to PDF files and labels like Approved, Paid or Confidential to authorize documents and communicate status clearly to recipients.
Being able to add text to PDF pages lets you fill in names, dates and notes without converting the file, and doing it in your browser keeps sensitive contracts and forms private.

Lower the opacity slightly for a realistic ink-stamp look.
Use the Draw tool to sign PDF online with a real handwritten signature.
Put the same stamp on multiple pages by duplicating it and switching pages.
After stamping, use Reduce PDF File Size if you need a smaller file for email.
