Three ways to add a signature
Draw your signature with a finger for a handwritten look, type your name and pick a script font, or import a signature image you already have. Save it once, and the next document takes a single tap.

Put it exactly where it belongs
Drag the signature across the page, pinch to resize, and rotate it to match the line. Snap guides help you line it up, and undo reverses any step.
Sign multi-page documents
Move between pages and sign each one, or apply the same placement to every page at once. Add initials, a stamp or a date wherever the form needs them.
Export a clean, flattened PDF
The exported PDF has your signature baked in, with no watermark and no ad. Share it straight back to email or chat, or save it to your device.
