Sign PDF on Windows
Adobe Acrobat is overkill for a simple signature. PrivaPDF works in your Windows browser — Chrome, Edge, or Firefox — and lets you sign any PDF for free.
No account needed · zero uploads, verifiable in DevTools
Adobe Acrobat Reader (the free version) on Windows can add a basic typed or drawn signature, but it's tucked inside a "Fill & Sign" panel that many users never discover, and the drawing tool via mouse is imprecise compared to touch or trackpad input.
PrivaPDF works the same way in Chrome, Edge, or Firefox on Windows — drop the PDF, draw or type a signature, place it, and download — without needing Acrobat Reader installed at all.
