How to Sign a PDF Online for Free Without Printing

By SnapPDF · 5 min read

Printing a document, signing it by hand and scanning it again wastes time. You can place your signature directly on a PDF from your computer or phone browser. This guide shows the quick way, and explains an important difference between a simple signature and a certificate-based digital signature.

How to sign a PDF with SnapPDF

  1. Open the PDF Editor and upload your document.
  2. Go to the page that needs your signature.
  3. Choose the signature tool and create your signature.
  4. Place it on the signature line and resize it until it fits.
  5. Download the signed PDF.

Tips for a neat signature

  • Draw slowly and keep it close to your normal handwriting.
  • Make it large enough to read, but do not let it touch the text around it.
  • Sign every page that needs it, and add the date if the form asks for one.

Visual signature vs certificate-based digital signature

Placing your signature on the page creates a visible mark, similar to signing on paper. Some processes, such as certain government or legal workflows, require a certificate-based digital signature that can be verified cryptographically. If you are not sure which one you need, ask the person or organization requesting the signature before you send the document.

Keep your signature private

Your signature is personal data. Many online signing tools upload your document and your signature to their servers. SnapPDF handles everything in your browser, so neither is sent anywhere.
