Is the PDF signing tool free?

Yes, completely free. No signup, no credits, no hidden fees.

Are my PDF files uploaded to a server?

No. All signing is done locally in your browser. Your files never leave your device.

Is this a legally binding electronic signature?

This tool creates a visual signature (image overlay) on the PDF. For legally binding e-signatures with audit trails, a certified e-signature service is required. However, for most informal documents, agreements, and internal use, this signature is sufficient.

Can I draw my signature on mobile?

Yes. Use your finger to draw your signature on the touch screen. The drawing canvas supports touch input on all mobile devices.

Can I add multiple signatures to one PDF?

Yes. After placing one signature, click 'Add Another Signature' to add a second signature, initials, or date to a different location on the document.

Can I sign multiple pages?

Yes. You can navigate between pages and place your signature on any page. Use 'Apply to All Pages' to stamp your signature on every page at once.

What signature styles are available?

Three modes are available: Draw (freehand with mouse or finger), Type (type your name and choose a handwriting-style font), and Upload (upload a photo or image of your handwritten signature).

Can I change the signature color?

Yes. When drawing or typing, you can choose black, blue, or red ink color.

Will the PDF quality be affected?

No. Signing only adds a transparent image layer on top of the PDF content. The original content is completely unchanged.

Can I sign a password-protected PDF?

Password-protected PDFs must be unlocked first using our Unlock PDF tool, then you can sign the unlocked file.

Sign on Mobile

Is This a Legal Electronic Signature?

This tool creates a visual signature — a high-quality image of your signature placed directly on the PDF. For most informal agreements, internal documents, consent forms, and everyday use, this is perfectly sufficient. For legally binding contracts requiring an audit trail and certificate, a certified e-signature service (like DocuSign) is required.
