Frequently Asked Questions
Are my PDF and signature uploaded to a server?
No. The PDF, the signature image, and all processing stay in your browser. Nothing is uploaded to PDFHelix or any third party.

Yes. Use the page arrows to choose the page, then click the preview to place the signature exactly where you want it.
Is this a digital certificate signature?

Can I sign a password-protected PDF?
Password-protected files are not supported directly. If you own the document, unlock it first and then sign the unlocked copy.
