Three Ways to Create Your Signature

✍️ Draw Your Signature

Use your mouse, trackpad, or finger (on touch devices) to draw your signature. This creates the most natural-looking result and mimics your actual handwriting.

⌨️ Type Your Name

Simply type your name and choose from signature-style fonts. Quick and professional, great when you need consistency across documents.

📷 Upload Signature Image

If you have a scanned image of your signature, you can upload it. This works well if you want to use your existing signature.

💡 Pro Tip: When drawing your signature, use smooth, confident strokes. If you make a mistake, just clear and try again — practice makes perfect!

Adding Additional Information

Besides your signature, you often need to add:

  • Date — When you signed the document
  • Printed name — Your name in regular text
  • Initials — For initialing individual pages

Are Electronic Signatures Legal?

Yes! Electronic signatures are legally valid in most countries:

  • USA — ESIGN Act (2000) makes e-signatures legal
  • EU — eIDAS regulation recognizes electronic signatures
  • UK — Electronic Communications Act 2000
  • Canada — PIPEDA and provincial laws
  • Australia — Electronic Transactions Act

For most everyday documents — contracts, agreements, forms — electronic signatures are fully binding.

⚠️ Exceptions: Some documents still require handwritten signatures or notarization, such as wills, certain real estate deeds, and court documents. Check your local requirements for sensitive legal documents.

Tips for Professional-Looking Signatures

Keep It Consistent

Use the same signature style across all documents. This looks more professional and helps with recognition.

Size Matters

Don't make your signature too small (hard to see) or too large (looks unprofessional). It should fit naturally in the signature area.

Use Dark Colors

Black or dark blue signatures look most professional and scan/copy well. Avoid light colors that might not print clearly.
