About the Sign PDF
Electronic signatures have clear legal standing on both sides of the Atlantic. In the United States the ESIGN Act of 2000 and state UETA adoptions give them the same effect as ink for most commercial agreements, and in the United Kingdom the Law Commission confirmed in 2019 that a simple electronic signature can execute most contracts.
This tool lets you draw your signature, choose the page and the position, and stamp it into the document — all inside your browser, so an unsigned agreement never gets uploaded anywhere. What it produces is a simple electronic signature: an image of your mark placed in the file. That is sufficient for a great many everyday agreements but is not the same thing as a certificate-based digital signature.
It's part of the PDF collection on Toolzy, a growing platform of 135+ free, privacy-first tools built for speed and a great experience on every device.
Also known as: signature, esign, sign, document.
