Use Whiteout for Clean Corrections

To replace outdated text, place a whiteout box over the original words and layer a new text box right on top with matching font size.

Hold Shift to Draw Straight Lines

When drawing arrows, callouts, or underline strokes, use consistent stroke widths to maintain a clean aesthetic.

Rotate Pages Before Adding Annotations

Ensure your pages are right-side up using the sidebar rotate tool before adding text or signatures.

Zoom in for Precise Signature Placement

Use the bottom zoom controls (up to 250%) to place signatures and initials accurately on tight signature lines.
