How to Sign a PDF in Safari Without Installing Anything
Safari is the default browser on every Apple device — iPhone, iPad, and Mac. While Apple includes a Markup feature that allows basic annotation, it was not designed as a dedicated PDF signing tool. The Markup drawing area is small, managing signatures across multiple pages is cumbersome, and adding typed text fields is limited.
SigPDF is a web-based PDF signing tool built to work perfectly in Safari. It provides a full signing experience: create your signature by drawing, typing, or uploading an image; place it precisely on any page of your PDF; add text fields for dates, initials, and other information; and download the finished document with your signature permanently embedded.
Signing on iPhone with Safari
On iPhone, SigPDF's interface is optimized for the smaller touchscreen. The signature pad captures smooth, natural-looking strokes from your finger. You can draw your signature in portrait or landscape orientation — turn your phone sideways for a wider signing area. Once your signature is created, tap on the PDF page to place it, then pinch to resize or drag to reposition.
Signing on iPad with Safari and Apple Pencil
The iPad experience is particularly compelling. SigPDF's signature pad fully supports Apple Pencil, capturing pressure-sensitive strokes that look remarkably close to a real pen-on-paper signature. The larger iPad screen gives you plenty of room to draw a precise, natural-looking signature. Whether you are using an iPad Air, iPad Pro, or iPad mini, SigPDF adapts to your screen size and provides a comfortable signing experience.
Signing on Mac with Safari
On Mac, you can draw your signature using the trackpad, a connected mouse, or type your name and choose from handwriting fonts. SigPDF takes full advantage of Safari's performance on macOS, rendering your PDF quickly and handling even large multi-page documents smoothly.
Privacy in Safari
Safari is known for its strong privacy features, including Intelligent Tracking Prevention and privacy reports. SigPDF aligns with this privacy-first philosophy. Your PDF is processed entirely within Safari using client-side JavaScript. The file never leaves your device — no uploads, no server-side storage, no third-party access. When you close the Safari tab, no trace of your document remains.
