The Sign PDF tool by PDFSetu is a high-speed, secure, browser-native utility designed to let you sign contracts, agreements, invoices, tax documents, and job offer letters directly from your computer, phone, or tablet. In today's fast-paced digital world, printing out documents just to sign them with a pen, scan them back, and email them is an outdated, time-consuming hassle.
Our online signature tool provides three flexible signing options: Draw your signature using your mouse, trackpad, or touchscreen stylus, Type your name using elegant cursive calligraphy fonts, or Upload a clean scanned photo of your handwritten signature. You can freely position, resize, and apply your signature to any page with pinpoint accuracy before generating an instant, print-ready signed PDF.
Signing official documents with PDFSetu requires zero software installation, zero account registration, and takes under a minute:
Your signature is one of your most sensitive personal credentials. When you use conventional cloud-based e-signature websites, both your signature graphics and your confidential legal contracts are transmitted across the internet to third-party databases. These files may be stored indefinitely, leaving you vulnerable to corporate data breaches, identity theft, or unauthorized access.
All canvas rendering and PDF manipulation happens locally inside your browser memory. Your documents and signature never touch external servers.
Because there is no server queue or network upload delay, documents are signed and compiled in milliseconds right on your device's processor.
No expensive monthly software subscriptions, no watermarks, no credit card required, and no hidden document limits.
