Digital Signature Generator — Free Online Tool

The Digital Signature Generator lets you draw a signature with a mouse, trackpad, or finger, or render your typed name in a handwriting-style font, and exports it as a transparent PNG you can drop into a PDF, a contract, or an email footer.

The transparency is the part that matters practically. A signature saved on a white background sits as a visible white rectangle over whatever is underneath it in a document, which looks obviously pasted. A transparent PNG sits on the page like ink. Drawing at a larger size than you need and scaling down also helps — a signature drawn small has visibly jagged edges once it is placed at document scale.

It is worth being clear about what this produces legally, because the terminology is genuinely confusing. This creates an *electronic signature* — an image of a signature applied to a document. That is legally valid for a wide range of everyday agreements in most jurisdictions, including under the US ESIGN Act and the EU's eIDAS regulation at its basic tier. It is not a *digital signature* in the cryptographic sense: there is no certificate, no key pair, and no tamper-evident binding to the document. For anything high-value, regulated, or likely to be disputed, a service that provides an audit trail and identity verification is the right tool, and for some jurisdictions and document types it is required.

Everything is rendered on canvas in your browser — your signature image is never uploaded, which is exactly as it should be for something this sensitive.

Our Digital Signature Generator is completely free to use with no signup required. For this tool, processing runs in your browser — your files and data stay on your device and are not uploaded to our servers.

Whether you are a developer, designer, student, or business owner, this tool is designed to save you time and make your workflow more efficient. Bookmark this page to access it whenever you need it — it will always be free.
