Frequently asked questions
Is the tool free?
Yes, it is free with no sign-up and no limit.
Are my files uploaded to a server?

No. It is a visible signature placed on the page as an image, not a digital signature backed by a certificate.
What is the best format for the signature image?
A PNG with a transparent background so the background does not cover the page text.
