Sign PDFs on Tablet

Tablets offer the ideal balance of portability and screen size for signing PDF documents. With a larger display than a phone and full touchscreen support, tablets let you view entire pages of a document, read the fine print, and draw a natural-looking signature with your finger or stylus. SigPDF is optimized for the tablet experience, providing a responsive interface that takes full advantage of the larger screen real estate. Whether you are using an iPad, a Samsung Galaxy Tab, a Microsoft Surface, a Lenovo Tab, or any other tablet, SigPDF works directly in your browser without requiring an app download.

Touch and stylus support are at the core of the tablet signing experience. SigPDF's signature drawing pad detects touch input and captures smooth, natural strokes whether you use your finger or a stylus. On tablets that support pressure-sensitive styluses — like the iPad with Apple Pencil, Samsung Galaxy Tab with S Pen, or Microsoft Surface with Surface Pen — SigPDF produces signatures with varying line thickness that look remarkably authentic. The drawing area automatically scales to your tablet's screen size, giving you plenty of room to create a comfortable, legible signature. If drawing is not your preference, you can type your name and choose a handwriting font, or upload a photo of your existing signature.

SigPDF works on every major tablet operating system. For iPads running iPadOS, SigPDF works in Safari, Chrome, and other browsers. For Android tablets (Samsung Galaxy Tab, Lenovo Tab, Amazon Fire, Google Pixel Tablet), it works in Chrome, Samsung Internet, Firefox, and other browsers. For Microsoft Surface and Windows tablets, it works in Edge, Chrome, and Firefox. The signing experience is consistent across all these platforms, which is a significant advantage if you use multiple devices or share signing workflows with colleagues who use different tablets. The tool supports multi-page PDFs, so you can scroll through a lengthy contract and place signatures, initials, and dates on every page that needs them.

Privacy is handled with care. SigPDF processes your PDF entirely within the tablet's browser. No files are uploaded to any server, ensuring that sensitive documents like contracts, legal agreements, medical forms, and financial paperwork stay on your device. This client-side processing also means the tool works reliably even on slower tablet internet connections or when you are offline (after the initial page load). Once you finish signing, download the completed PDF directly to your tablet. From there, you can share it via email, messaging apps, cloud storage, or AirDrop (on iPad). SigPDF makes tablet-based PDF signing fast, private, and hassle-free regardless of which tablet you own.
