Signing a PDF should not require printing, scanning or creating an account with an e-signature service. PDFkitt opens the signature dialog as soon as your file loads: draw your signature with a mouse, finger or stylus, type your name in one of three handwriting styles, or upload a picture of your real signature.
Place it on the signature line, resize it, add today’s date and initials, and download the signed PDF. Signatures are stored in your browser on this device so the next document takes seconds. Nothing — not the document, not the signature — is ever uploaded.

Frequently asked questions
Is an electronic signature legally valid?
For most everyday agreements, yes (for example under ESIGN in the US and eIDAS in the EU). It is not a certificate-based digital signature; if a recipient specifically requires one, use the service they name.
Can I sign on my phone?
Yes — drawing with a finger on a phone screen usually gives the best result.
Can I add initials on every page?
Save a second signature with just your initials and insert it on each page, or insert once and use Copy to every page.
