Frequently Asked Questions (FAQ)
Are electronic signatures created here legally binding?
Under the US ESIGN Act and EU eIDAS regulations, electronic signatures placed with the consent of the signing parties have the same legal standing as wet ink signatures.
Does OmniTool Hub store a copy of my signature?
No. Signatures are drawn on local HTML5 canvas elements and burned directly into the PDF. Nothing is saved or uploaded to any server.
Can I save my drawn signature for repeated use on multiple pages?
Yes. You can save your signature in your local browser storage so it is instantly available across multi-page contracts.
Can I add date stamps and initials alongside my signature?
Yes. The toolbar includes one-click buttons to add the current date, custom text fields, and initials.
