How do I add a signature to a PDF?

Upload your PDF, then draw, type, or upload an image of your signature. Position it anywhere on the document and download.

Is my signature stored anywhere?

No. Everything is processed locally in your browser. Your signature and document never leave your device.

Is a digital signature legally binding?

Electronic signatures added through our tool are generally considered legally binding in most jurisdictions, similar to handwritten signatures.

Is this tool free and private?

Yes, 100% free. All processing happens in your browser — your files never leave your device.

Is this a legally binding electronic signature?

This tool creates visual signatures. For legally binding e-signatures, you may need a certified e-signature service depending on your jurisdiction.

Can I draw my signature or upload an image?

Both! Draw your signature directly on the canvas, or upload a signature image from your device.

Where is my signature placed?

Signatures are placed in the bottom-right corner of the last page. Custom positioning is coming soon.
