FAQs
Is a digital signature legally binding?
Digital signatures can be legally binding in many jurisdictions when properly executed. However, this tool creates signature images, not cryptographic digital signatures.
What format should I use?
PNG with transparency is best for inserting into documents and emails. SVG is ideal for scalable signatures. JPG works but has no transparency.
What size should my signature be?
For documents: 300-500px wide. For email: 200-300px wide. For business cards: 150-200px wide. Higher resolution ensures quality when resized.
Are digital signatures legally binding?
Yes in most countries under E-SIGN Act (US) and eIDAS (EU). Requirements: signer identity, intent to sign, consent to electronic signatures, record retention. Not valid for: wills, court orders, some real estate (varies by location). Consult lawyer for legal documents.
What is the difference between electronic and digital signatures?
Electronic signature: any electronic sign-off (typed name, image, click). Digital signature: encrypted with cryptographic certificate for authentication and tamper-proof verification. Digital signatures more secure for legal/financial documents. Electronic sufficient for informal agreements.
How do I add signature to PDF documents?
Methods: 1) PDF editors (Adobe, Preview, PDFelement), 2) Online tools, 3) Print > Sign > Scan, 4) Digital signature certificates. Save signature as PNG with transparency. Insert as image. Or use PDF signature fields for proper digital signatures.
