Create a Digital Signature Online — Free, Private, No Account
Draw your signature once and download it as a transparent PNG you can drop into a PDF, Word document, Google Doc, invoice, or form. The canvas runs entirely in your browser, so your signature is never uploaded, stored, or seen by anyone else. No account, no watermark, and no limit on how many signatures you create.
How to create a digital signature online
- Pick a pen color and stroke width — a thinner stroke usually looks more natural for a full signature.
- Draw your signature with a mouse, trackpad, stylus, or your finger on a touchscreen.
- Clear and redraw until it looks right.
- Download the transparent PNG and insert it wherever the document expects a signature.
Why use this signature generator?
- Nothing leaves your device: the signature is drawn and exported locally with the Canvas API — no server, no tracking.
- Truly transparent background: no white box behind the writing, so it sits cleanly over a signature line.
- Works on phones and tablets: draw with your finger and rotate to landscape for more room.
- Free and unlimited: no sign-up, no watermark, no daily cap.
Electronic signature or digital signature?
This tool creates an electronic signature image — an electronic mark that shows your intent to sign. It is not a certificate-based digital signature, so it does not verify your identity cryptographically or create an audit trail. That makes it a good fit for routine approvals, invoices, letters, and forms, and the wrong fit for regulated or high-value agreements. Read the full comparison before signing something important.

Frequently Asked Questions
How do I create a digital signature online for free?
Draw your signature on the canvas with a mouse, stylus, or finger, then click Download Signature. You get a transparent PNG you can insert into a PDF, Word document, or Google Doc. It is free and needs no account.
Is this a digital signature or an electronic signature?
It creates an electronic signature image. A certificate-based digital signature uses cryptography to verify identity and detect later changes to a document; this tool does not do that. For routine approvals and forms, an image signature is normally accepted.
Can I add the signature to a PDF?
Yes. Download the transparent PNG, then place it on the signature line with any PDF editor that can insert an image or stamp. Our guide on adding a signature to a PDF walks through each step.
Is the downloaded signature transparent?
Yes. The PNG has no background, so the document shows through behind your signature instead of a white rectangle.
Does it work on a phone or tablet?
Yes. The canvas supports touch drawing. Rotate your device to landscape for more room and draw slowly for a cleaner line.
Is my signature private?
Yes. Drawing and PNG export happen entirely in your browser. The signature is never uploaded to a server, and we cannot see it.
