How to Sign a PDF Online

Printing a document just to sign and rescan it wastes time. Here's how to add a real signature to a PDF entirely on-screen.

Why print-sign-scan is disappearing

Printing, signing, and scanning a document introduces friction most people simply skip these days — smudged ink, misaligned scans, and lost paperwork. On-screen signing solves this by letting you draw your signature once and place it exactly where it needs to go, with the rest of the document untouched.

Two common ways to sign a PDF

Is a drawn signature legally valid?

In many jurisdictions, a simple electronic signature (like a drawn signature stamped onto a document) is legally recognized for everyday agreements — leases, informal contracts, internal forms. However, requirements vary significantly by country and document type, and some contracts (certain real estate transactions, notarized documents, specific regulated industries) legally require a certified e-signature service with an audit trail, not just a visual signature. When in doubt for anything high-stakes, check what your specific document or jurisdiction requires.
