How do I electronically sign a PDF for free?

Our tool lets you sign a PDF document at no cost. Just upload your PDF, select 'Draw' or 'Type' to create your signature, place it on the page, and download. There are no limits and no watermarks.

Can I create an image of my signature?

Yes. You can draw it on a piece of paper, take a photo, crop it, and upload it. Or, for a cleaner look, use the 'Draw' feature in our tool to create a crisp digital version instantly.

Is it secure to sign my confidential documents online?

Yes. Our tool is exceptionally secure because it is 100% client-side. Your document and your signature image are never uploaded to our servers. All processing happens locally on your device.

I need to sign and fill out text fields. Can I do that?

This specific tool focuses on adding the signature image. For filling out 'Name', 'Address' or checking boxes, use our PDF Annotator tool. You can fill the form there and then sign it.

Is this signature legally binding?

In most cases for standard business agreements, yes. Electronic signatures are recognized by the ESIGN Act and other global laws as valid evidence of intent to sign. However, for high-level legal documents (wills, deeds), check your local laws.

Can I sign a PDF on my iPhone?

Absolutely. Our website is mobile-friendly. You can upload a PDF from your iPhone files, use your finger to draw your signature on the screen, and download the signed file instantly.
