Sign PDF in Microsoft Edge — No Downloads

Microsoft Edge is the default browser on Windows 10 and Windows 11, making it one of the most widely used browsers in the world. Edge includes a capable built-in PDF reader with annotation tools, highlighting, and a basic drawing feature. However, Edge's PDF tools are designed for annotation, not for document signing. There is no dedicated signature feature, no handwriting font options, and no way to create a reusable signature.

SigPDF fills this gap. It is a web application that runs directly in your Edge browser tab. Open SigPDF, upload your PDF, create your signature by drawing, typing, or uploading an image, place it on the document, and download the signed file. The entire process takes less than a minute, and your PDF never leaves your device.

Edge's Built-in PDF Tools vs SigPDF

Microsoft Edge's PDF reader is impressive for basic tasks — it can display PDFs, fill form fields, add text, draw freehand annotations, and highlight text. But for document signing specifically, SigPDF offers a more complete solution:

• Dedicated signature creation — Draw a smooth signature with your mouse or touchscreen, type your name with handwriting fonts, or upload a signature image. Edge's Draw tool is a freehand annotation tool, not a signature tool.
• Signature placement — Click anywhere on the PDF to place your signature. Resize and reposition it precisely.
• Professional results — Signatures created with SigPDF are permanently embedded in the PDF, producing a clean, professional document suitable for business use.
• Text fields — Add dates, initials, and other text annotations alongside your signature.

Privacy in Microsoft Edge

When you sign a PDF with SigPDF in Edge, your document stays on your device at all times. The PDF is loaded into your browser's memory, the signature is applied using client-side JavaScript, and the finished document is generated locally. No file is ever uploaded to SigPDF's servers or any third-party service. This is especially important for Windows users in corporate environments where document confidentiality is critical.
