Comment PDF

For those who need to annotate PDF files, you can click "Comment". With this function, the two sections that are provided are annotations and drawing markups. In "Annotations", you can easily highlight, underline, strikethrough text, or even insert a sticky note for better illustration and review.


Upon drawing markups, you are allowed to add arrows, lines, ovals, and rectangles. If you place a markup at the wrong place, you can go to "Edit" > "Undo" to remove that markup.
