Frequently asked questions

Can I undo a stroke I got wrong?

Yes. Undo and redo step back through your strokes, and Clear all removes every stroke on the page so you can start again.

Can I change the ink color and thickness?

Yes. Pick any color and set the stroke width before drawing — a thin dark line for corrections, a thicker bright one for emphasis.

Does drawing work with a finger or stylus?

Yes, on touch-capable devices supported by your browser.

Is this a digital signature?

No. Draw is freehand annotation. For a visual signature stamp, use Sign PDF.

Draw vs highlight — which should I use?

Draw for freehand ink. Highlight for translucent marker boxes over regions.

Do I need an account?

No. Drawing is free without registration.
