The Ultimate Guide to Creating Digital Signatures Online
Everything you need to know about creating, using, and securing your handwritten signature in the digital age—without a scanner.

In today's remote-first world, printing, signing, and scanning documents is a relic of the past. A digital handwritten signature allows you to sign contracts, agreements, and letters instantly from your computer or phone.
Using a tool like Signature Sketch ensures that your signature looks professional and authentic, without the jagged lines often caused by scanning low-quality paper.

How to Create a Perfect Signature
Creating a digital signature that looks like your real one can be tricky with a mouse. Here are some tips to get the best result using our free generator:
- Use a Touchscreen if Possible: While mice work, using your finger on a smartphone or tablet (iPad) yields the most natural results.
- Adjust the Width: A real pen has varying thickness. Use the "Width" slider to match your preferred pen style (e.g., ballpoint vs. marker).
-
Choose the Right Color:
- Black: Best for formal contracts and government forms.
- Blue: Used to distinguish an original from a photocopy.
- Red: Typically reserved for grading or internal approvals.
