Sign PDFs Without Printing

The traditional way to sign a PDF has been absurdly wasteful: print the document, sign it with a pen, scan it back into a digital file (or photograph it with your phone), and then email or upload the scanned version. This process wastes paper and ink, requires access to a printer and scanner, produces a lower-quality document (due to scanning artifacts), and takes far more time than necessary. SigPDF eliminates every step of this outdated workflow. You sign the PDF digitally, directly in your browser, and download the result. No printer needed, no scanner needed, no paper wasted, and the signed document looks cleaner and more professional than any scanned copy ever could.

Going paperless with PDF signing is not just about convenience — it is about environmental responsibility. The average office worker uses approximately 10,000 sheets of paper per year, and a significant portion of that is for printing documents that only need a signature. By signing digitally with SigPDF, you eliminate paper waste, reduce ink and toner consumption, and decrease the energy used by printers and scanners. If your organization signs hundreds or thousands of documents annually, the environmental impact of switching to digital signatures is substantial. SigPDF makes this transition effortless because it works in any browser on any device, with no software to install and no learning curve.

Many people print PDFs for signing because they believe a handwritten signature is required or that digital signatures are not legally valid. In reality, electronic signatures are legally recognized in most countries around the world. In the United States, the ESIGN Act and UETA make electronic signatures legally binding for most transactions. In the European Union, the eIDAS regulation provides a legal framework for electronic signatures. In the United Kingdom, the Electronic Communications Act recognizes electronic signatures. SigPDF creates electronic signatures that meet these legal standards for the vast majority of common documents, including contracts, agreements, consent forms, invoices, and more. Only a small number of document types (such as wills, certain real estate deeds, and court orders) still require wet ink signatures in some jurisdictions.

SigPDF offers multiple ways to create your signature digitally. You can draw it with your mouse, touchpad, finger, or stylus for a signature that closely mimics your handwritten one. You can type your name and choose from several handwriting-style fonts for a clean, consistent look. Or you can upload an image of your existing signature if you have one saved. Beyond signatures, SigPDF lets you add text fields for dates, initials, printed names, and other information that documents typically require alongside a signature. The signed PDF downloads as a standard file that any recipient can open with any PDF reader — no special software needed. It works on Windows, Mac, Linux, iPhone, Android, iPad, Chromebook, and any device with a modern browser.
