Sign PDF on Windows: built-in options vs this tool
Windows has no built-in PDF signing. Edge can draw on a PDF, but it is ink, not a placed signature. This page lets you draw once and place the signature cleanly.
It runs in Edge, Chrome or Firefox on Windows 10 and 11, with no software to install and nothing to uninstall later.
Private by design
Your file is processed by your own browser, in memory. It is never uploaded, stored or seen by anyone, and the page’s security policy blocks it from sending data to other servers.

Is an electronic signature legally valid?
In the US (ESIGN Act), the EU (eIDAS) and many other countries, electronic signatures are legally recognised for most contracts. Some documents, such as wills or certain government forms, have special rules; check with the recipient if unsure.
What’s the difference between an electronic and a digital signature?
An electronic signature is a visible mark of agreement, like the one this tool adds. A digital signature is a cryptographic certificate embedded in the file that proves who signed and that nothing changed afterwards. This tool does not add certificates.
Is it safe to use with confidential documents?
Yes. The file is opened by your own browser and processed in your device’s memory. It is never uploaded, so no server, including ours, ever receives a copy. That makes it suitable for contracts, IDs, medical or bank documents.
