How to Sign a PDF on Windows
Windows has no dedicated signing app, but two free options cover most needs: Adobe Acrobat Reader and the drawing tool built into Microsoft Edge's PDF viewer.
Step by step
- Open the PDF in Adobe Acrobat Reader. Install the free Acrobat Reader from Adobe's website if you do not have it, then open the PDF.
- Open Fill & Sign. Find the fill and sign tools in the tools menu. Adobe updates its interface regularly, so use the tool search if you cannot see them.
- Add your signature. Choose to sign yourself and add a signature. You can type, draw or upload an image of your signature.
- Place and resize. Click where the signature belongs and adjust its size. Add text for the date if needed.
- Save. Save the file. Use Save As to keep the original unsigned copy.
Using Microsoft Edge instead
Edge opens PDFs by default on many Windows PCs. Its built-in PDF viewer has annotation tools in the toolbar, including a drawing tool you can use to write your signature with a mouse, pen or touchscreen, and a text tool for the date. Save the file when you are done.
Drawing with a mouse can look rough. A saved, reusable signature in Acrobat Reader or a typed signature often looks cleaner.
A browser-based option
If you would rather not install anything, eSignSimple's free Sign PDF tool (/tools/sign-pdf) runs in your browser: the file is processed on your device and is not uploaded. You can draw or type a signature, add the date, and download the signed PDF.
It works in Edge, Chrome or Firefox on Windows.
