What You Can Do With This Sign PDF Tool
Sign PDF Online is a free web app that allows you to sign documents digitally without printing them. You can create your signature in three different ways: drawing it with your mouse/trackpad, typing your name and selecting from highly stylized cursive handwriting fonts, or uploading a photo/scan of your physical signature as an image.
Once placed, you can resize and reposition the signature block anywhere on the document. When you apply the signature, the tool processes the PDF document using math-based coordinate mapping to burn the signature elements directly into the PDF structure, ensuring it displays permanently on any PDF viewer.
