3 Ways to Create Your Electronic Signature

✏️ Method 1: Draw Your Signature

Use your mouse, trackpad, or touch screen to draw your signature naturally. This produces the most authentic-looking result and closely matches your handwritten signature. Works great on mobile touchscreens.

Best for: Contracts, legal documents, anything requiring a personal signature feel.

⌨️ Method 2: Type Your Signature

Type your name and select a signature font (cursive, printed, etc.). Fast and consistent — ideal if you need to sign many documents with an identical-looking signature.

Best for: Internal documents, forms, approvals where exact signature style is less critical.

🖼️ Method 3: Upload Signature Image

Scan or photograph your handwritten signature on white paper, then upload it as a PNG (preferably with transparent background). This gives you a reusable, authentic-looking signature from a real pen.

Best for: Business contracts, legal agreements, documents where your exact signature is required.
