Why use Sign PDF on PDF NOVA
Files stay on your device
Processing happens in your browser. Your document is never uploaded to a server, so there is nothing to delete afterwards.
Draw, type or upload
Use a mouse, trackpad, stylus or finger — or type your name in a handwriting style.
No sign-up, no watermark
Open the page and start working. Results are clean PDFs with no branding added.
Processing on your device
Sign PDF processes your file in your browser on your device. The file is not uploaded for processing. Download the result to keep a permanent copy. Your active PDF is saved locally in this browser for recovery across refreshes. Close Document removes it; recovery expires after 24 hours and is cleaned up when PDF NOVA next opens. Unsaved changes are not restored.

Frequently asked questions
Are my files uploaded anywhere?
No. This tool runs entirely in your web browser using JavaScript and Web Workers. The file is read from your device, processed in memory and saved back to your device.
Is an electronic signature legally binding?
In many jurisdictions (including under the US ESIGN Act and the EU eIDAS regulation) simple electronic signatures are legally valid for most agreements. Some documents require advanced or qualified signatures — check the requirements for your document.
What is the difference between a signature image and a digital signature?
A signature image shows your signature on the page — that is what this tool adds. A cryptographic digital signature additionally proves the document has not changed since signing; certificate-based signing is not available yet.
