- Draw or type your signature.
- Place it on the page and adjust its size.
- Download the signed PDF.
Frequently asked questions
Is the signature legally binding?
It depends on your country and the document. OpenToola provides a practical signature, not a qualified electronic signature. Check the applicable rules.
Can I sign several pages?
Yes. Place the signature on each page you need, then download the PDF.
