Frequently asked questions
Is signing done privately?
Yes. Your PDF and signature never leave your device — everything happens in your browser.
Can I draw and type?
Either one. Use the Draw tab to sign by hand, or the Type tab to set your name in a signature font.
Can I resize and reposition the signature?
Yes. Drag the signature anywhere on the selected page and use the size slider to make it larger or smaller.
Is this a legally binding e-signature?
It adds a visible signature image to your document, which is fine for most everyday agreements. For regulated or qualified e-signatures, use a certified provider.
