Frequently Asked Questions
Is it free?
Yes. No signup required.
Is my file safe?
Yes — your PDF is processed entirely in your browser and never uploaded.
Is this a legally binding signature?
No. This adds a visual signature image to your PDF — it isn't a certified, legally binding e-signature under eIDAS or the U.S. ESIGN Act, and there's no audit trail or certificate. For contracts that require legal certification, use a dedicated e-signature service.
How do I create a signature?
Draw it with your mouse or finger, type your name in a handwritten-style font, or upload an image of your signature.
Can I sign every page at once?
Yes. Turn on "Add to every page" and your signature is placed in the same spot on every page.
Can I move or resize my signature?
Yes. Drag it to position it, and use the size slider to resize it before signing.
