Sign PDF Online is a free online tool that lets you add a digital or handwritten signature to any PDF document. Draw your signature using your mouse or touchscreen, type it in a cursive font, or upload an image of your handwritten signature. Position and resize the signature anywhere on the page — you can place it on signature lines, next to text, or in designated signature fields. The tool supports multiple signatures on different pages and lets you add dates, initials, and text annotations alongside your signature. All processing happens locally in your browser — your PDF and signature are never uploaded to any server. There is no file size limit, no sign-up, and no watermark. It is perfect for signing contracts, NDAs, authorization forms, business agreements, school permission slips, rental applications, and any document that requires your signature before submission. The signed PDF maintains the original document quality and formatting. Works on Windows, Mac, Linux, iOS, and Android.
