Electronic image versus digital certificate
This tool creates a visible electronic signature by embedding your drawing as an image. Certificate-based digital signatures additionally use cryptography to detect later document changes and associate the signature with a certificate identity. Check the recipient’s legal and technical requirements before choosing a signing method.
FAQ
Is this a cryptographic digital signature?
No. It places a visible electronic signature image on the PDF. It does not create a certificate-backed digital signature or independently verify signer identity.
Can I draw or type my signature?
Yes. Draw with a mouse, pen, or touch input, or switch to the typed-name style.
Can I choose the page and position?
Yes. Select a page number, then use horizontal, vertical, and width controls to place the signature preview.
Will existing PDF content change?
The tool embeds a PNG signature on the selected page and preserves the rest of the loaded PDF structure where supported by the PDF library.
Is my PDF uploaded?
No. The PDF and signature are combined locally in your browser, and the signed file is exposed through a temporary download URL.
