How to fill out and sign a PDF document on Windows 11

When someone emails you a contract, tax form, or lease agreement, you don't need to print it out, sign it with a physical pen, and scan it back onto your computer. You also don't need to pay for an expensive Adobe subscription just to drop a signature onto a page.

Instead, you can use the software that is already sitting on your computer. Microsoft Edge, the default web browser in Windows 11, features a highly capable, built-in PDF editor that lets you type into forms and draw or type a legal signature in seconds.

🔒 Privacy warning: Avoid uploading sensitive documents—like tax forms, bank statements, or employment contracts—to free online PDF signers. These platforms store your documents on external servers, posing a major security risk for your personal data. Always use native, local tools instead.

Method 1: Use Microsoft Edge (no software required)

Because Microsoft Edge handles PDF files natively in Windows 11, it is the absolute fastest tool for basic form filling and signing.

  1. Open the PDF file in Microsoft Edge. To do so, right-click the PDF.
  2. Go to Open with.
  3. Click Microsoft Edge.
  4. To fill in blank spaces or form fields, click the Add text icon in the top toolbar (it looks like a letter T in a box [T]).
  5. Click anywhere on the document where you need to type and begin entering your information. You can use the small floating menu to change the text color or size.
  6. To add your signature, click Draw or the fountain pen tip icon in the top toolbar.
  7. Click the downward arrow next to the pen icon to select black ink and adjust the thickness to look like a real pen.
  8. Use your mouse cursor (or a stylus/finger if you have a touchscreen) to draw your signature directly on the signature line.
  9. Click the save icon (the floppy disk) in the top-right corner to save your changes.

Method 2: Use PDFgear (completely free desktop app)

While Microsoft Edge is perfect for standard documents, some official government or tax forms use interactive checkboxes and complex fields that web browsers struggle to process. For these, a dedicated app like PDFgear is a fantastic, completely free solution that doesn't hide premium features behind a paywall.

  1. Download and install the free PDFgear app from their official website.
  2. Open PDFgear, click Open File, and select your PDF document.
  3. If the PDF is an interactive form, simply click into any highlighted box to type your information. If it is a flat document, click the Form tab at the top > Add Text to add text anywhere.
  4. To sign the document, click on the Form tab at the top and select Signature > Create Signature.
  5. Choose your preference: you can Type your name to generate a clean script, Draw your signature using your mouse, or upload an image (Picture) of your handwritten signature. Click OK.
  6. Click on the document where you want to place the signature, adjust its size by dragging the corners.
  7. Press Ctrl + S on your keyboard or click the save icon (the floppy disk) in the top-left corner to save your signed file.
