Draw your signature, drop your PDF, choose where it goes, everything stays on your device.
Draw your handwritten signature on a canvas and stamp it visually onto one or more pages of a PDF. This is a quick way to add a visible signature image to forms, letters, or internal documents.
Important: this tool creates a visual (image-based) signature overlay. It is NOT a cryptographic or certificate-based electronic signature and does not carry legal weight equivalent to a qualified digital signature. For legally binding e-signatures, use a dedicated signing platform.
No. Your PDF is parsed and rewritten by pdf-lib in your browser tab, the document is loaded into memory on your own device, your signature drawing (captured on a canvas as a PNG) is embedded and placed on the chosen pages there, and the new PDF is serialised in memory and offered as a local download. Nothing reaches Sunasty or any third party. Open your browser's DevTools, go to the Network tab and watch: no request carries your file.
No. This tool stamps a hand-drawn image onto the PDF, it is a visual mark, not a cryptographic e-signature tied to a certificate. It does not comply with eIDAS, ESIGN, or equivalent standards. For legally binding signatures, use a qualified electronic signature provider.
Yes. Once drawn, your signature can be placed on any page of the current document. You can also save the signature image locally and reload it for future sessions.
Yes, once the page has loaded. Because the processing happens on your device, you can disconnect from the network and the tool keeps working. This is the clearest proof that your data never leaves your machine.
