Why drawing produces a more natural signature
A typed signature uses a pre-made cursive font applied to your name — quick, but generic; everyone who types "Jane Smith" gets the identical signature shape. Drawing captures your actual hand movement, stroke by stroke, which produces something visually closer to how you'd sign on paper, and feels more personal for documents where that matters.
Getting a clean result
Drawing with a mouse is the least precise input method; a trackpad or touchscreen (finger or stylus) generally produces smoother results. PrivaPDF's canvas lets you clear and redraw as many times as you want before placing it, and you can resize the final signature once it's positioned on the page — all before it's flattened permanently into the PDF.
