Frequently asked questions

How do I create my signature?
Two options: draw it directly on the screen with your finger or mouse, or import an image (PNG or JPEG). A PNG with a transparent background will provide the best result.
Can I resize my signature?
Yes. Once placed on the page, the signature can be moved, resized, and rotated freely.
Can I sign multiple pages?
Yes. In the editor, drop your signature on each desired page to initial the entire document.
Does the signature have legal value?
This is a visual signature. For a qualified electronic signature, a certificate is required.
