Frequently Asked Questions

How do I change the color of a rectangle after I draw it in a PDF?

Right-click on the edge of the drawn rectangle, select 'Properties', and navigate to the 'Appearance' tab. From there, you can change both the border color and the fill color.

Can I draw a perfect square using the rectangle tool?

Yes. While dragging your cursor to draw the rectangle, press and hold the 'Shift' key on your keyboard. This constrains the proportions and creates a perfect square.

Why are the comment tools grayed out in my PDF?

If the commenting tools are inactive, the PDF is likely protected by the author. Go to File > Properties > Security to check if commenting is permitted. You may need a password to unlock these features.
