What kind of signature is this?
The tool stamps a picture of your signature onto the page, the same as signing a printout and scanning it. That is accepted for many everyday documents, but it is not a certified digital signature: it carries no cryptographic proof of who signed or whether the file changed afterwards. For legally sensitive documents, check what the other party requires.
Making a good signature image
Drawing works best on a touch screen or with a stylus; use a mouse more slowly for smoother lines. A transparent PNG blends into the page, so if you upload a photo of a signature, use dark ink on white paper in good light. The drawn and typed signatures are cropped automatically and saved with a transparent background.
