Add a signature image to a PDF

This tool places a visual signature image. It is not a cryptographic digital signature and may not satisfy legal or organizational requirements for digital certificates.
FAQ
Is this the same as a certificate-based digital signature?
No. It adds a visible signature image only.
What image works best?
A cropped PNG with a transparent background usually gives the cleanest result.
An image signature is not an identity check
Place the signature image only where the recipient permits it. Review the final placement at normal zoom; a pasted graphic is not equivalent to a certificate-based digital signature or a guarantee of legal acceptance.
