Do I need to print and scan the document?

No. The signature is added digitally to the original PDF, so the text stays sharp and selectable, and the file barely grows in size.

How do I place the signature exactly where I want?

Set the page and the position as percentages: X from the left edge and Y from the top. For example, X 60% and Y 85% puts it near the bottom right, where signature lines usually are.

Can I sign several pages?

Sign one page, download the result and upload it again to sign the next one. Each pass adds the signature to the page you choose.

Is it a legally valid signature?

It is a simple electronic signature (an image of your handwritten signature), accepted for many everyday documents. Contracts that require an advanced or qualified signature need a digital certificate.

Can I use a signature I already have?

This tool uses a signature drawn on the spot. To prepare a cleaner one first, create it in Signature generator .
