Windows does not include a built-in PDF signature tool. Microsoft Edge can annotate PDFs but does not support proper e-signatures. Here's how to sign any PDF on Windows for free — in your browser, with no software installation.
Go to pdfeditor.onl/sign-pdf in any browser on your Windows PC. Chrome and Firefox provide the best experience; Edge works well too.
Drag the PDF from Windows Explorer directly onto the browser window, or click the upload area to browse.
Tip: In Windows 11 and 10, you can drag a file from File Explorer onto a browser tab as a quick upload shortcut.
Draw your signature with the mouse on the canvas, type your name in a handwriting-style font, or upload a PNG image of your handwritten signature. Drag and resize to fit the signature field.
Click Download Signed PDF. The file saves to your Downloads folder.
Yes. pdfeditor.onl runs entirely in your browser — no download or installation required on Windows.
Windows 10 and 11 include Microsoft Edge which can draw freehand on PDFs. However, this produces an ink annotation rather than a proper e-signature field.
Yes. The operating system or browser used to create the signature does not affect its legal validity.
