Why Sign PDFs Digitally?
Printing, signing by hand, scanning, and emailing back wastes time and paper. Electronic signatures are legally recognised in most countries under laws like the ESIGN Act (USA), eIDAS (EU), and equivalent regulations worldwide. A digital signature on a PDF is as binding as a handwritten one in most business contexts.
Three Ways to Add Your Signature
Draw: Use your mouse or touchscreen to draw your signature directly.
Type: Enter your name and choose a handwriting-style font.
Upload: Upload an image of your handwritten signature (JPG or PNG, transparent background works best).

Is a Digital Signature the Same as an Electronic Signature?
For most business purposes, yes. The term "digital signature" technically refers to cryptographically verified signatures (like those in Adobe Sign or DocuSign) that provide identity verification and tamper-proofing. For everyday document signing — agreements, approvals, forms — an electronic signature (an image of your signature placed on a PDF) is sufficient and legally valid.
