Mark Up a PDF Like on Paper
Pick a tool, choose a colour and draw straight on the page: highlight a sentence, circle a figure, point an arrow at a detail, scribble a quick note in the margin or pin a sticky note with a comment. Undo the last mark or clear the page whenever you like.
Highlights, pen strokes and shapes are drawn into the page so they look the same in every PDF viewer. Sticky notes are saved as real PDF comments, so Acrobat, Preview and the browser viewers show them as note icons you can open.
Good to Know
Your original page content stays untouched and selectable; the marks sit on top. To remove marks later, mark up from the original file again. Combine annotating with signing and stamping in the PDF Workspace.
