Sign PDFs on Samsung Galaxy Devices

Samsung Galaxy devices are among the most popular smartphones and tablets worldwide, and millions of Samsung users need to sign PDF documents regularly. Whether you own a Galaxy S24, Galaxy A series, Galaxy Z Fold or Flip, Galaxy Tab S series, or any other Samsung device, SigPDF provides a seamless PDF signing experience directly in your browser. There is no app to download from the Galaxy Store or Google Play Store. SigPDF works in Samsung Internet (Samsung's built-in browser) as well as Chrome, Firefox, and any other browser installed on your device. Simply open the website, upload your PDF, and sign it using your finger on the touchscreen or your S Pen if your device has one.

Samsung Galaxy Note and Galaxy S Ultra users with the S Pen have a particular advantage when signing PDFs. The S Pen is a pressure-sensitive stylus that produces incredibly natural signatures, capturing the nuances of line thickness and stroke variation that make your signature look authentic. SigPDF automatically detects S Pen input and optimizes the signature drawing experience for stylus use. Galaxy Tab S series tablets with S Pen support are especially well-suited for document signing thanks to their larger screens, which provide a comfortable viewing area for reviewing contracts and other multi-page documents before signing. Even without an S Pen, Samsung's high-quality touchscreens make finger signing smooth and responsive.

Samsung Internet is the default browser on Galaxy devices, and SigPDF is fully optimized for it. Samsung Internet supports all the web standards that SigPDF relies on, including the Canvas API for signature drawing, the File API for PDF upload and download, and touch event handling for mobile interactions. If you prefer Chrome or another browser, SigPDF works equally well. The signing interface automatically adapts to your Samsung device's screen size and orientation. On Galaxy phones, the interface is compact and touch-friendly. On Galaxy Tab tablets, the interface expands to take advantage of the larger display. On Galaxy Z Fold devices, SigPDF adapts to both the cover screen and the inner foldable display.

Privacy is a priority for Samsung users, and SigPDF delivers. When you sign a PDF on your Samsung device, the document is processed entirely within your browser. It is never uploaded to any server. This is especially important for sensitive business documents, employment agreements, legal contracts, and personal financial forms. After signing, the PDF downloads directly to your Samsung device's Downloads folder. You can then share it via Samsung Email, Gmail, WhatsApp, Telegram, or any other app. If you use Samsung DeX to connect your phone or tablet to a monitor, SigPDF works in DeX mode as well, providing a desktop-like signing experience on the big screen.
