How to Sign a PDF on Windows 10 and 11

Windows PCs do not come with a dedicated signature application pre-installed, but you don't need to purchase Microsoft 365 or Adobe Acrobat to sign a document. Here is the easiest way to sign a PDF on Windows.

Signing PDFs in Windows using Web Tools

By using an in-browser client-side tool like PrivaPDF, you can sign any document without installing bloated third-party software. It works on all Windows web browsers, including Microsoft Edge, Google Chrome, and Mozilla Firefox.

Step-by-Step Instructions:

Open the PrivaPDF Sign PDF Tool in any browser.
Select or drag the PDF file from your Windows File Explorer.
Create your signature (draw with mouse/pen, or type with clean signature fonts).
Place, scale, and align the signature block on the page.
Click "Download" to save the signed PDF.

Don't trust us.
Verify it yourself.

Open DevTools → Network while converting. You'll see zero outbound requests. Every byte stays inside your browser tab.

Common questions

Does Windows have a built-in PDF signer?

Microsoft Edge lets you draw on PDFs, but it doesn't have a structured signature management tool. PrivaPDF offers a dedicated signing interface where you can save, resize, and position signatures.

Can I use a stylus to sign on Windows?

Yes, if you have a touchscreen Windows laptop or tablet, you can draw your signature naturally with a stylus or your finger.

Is my file uploaded to a server?

No. All processing happens entirely in your browser using WebAssembly. Your file never leaves your device.
