About Annotate PDF
Mark up a PDF for review or study. Highlight key passages, draw boxes around sections and add your own notes anywhere on the page, then download the annotated copy. It's ideal for checking drafts, marking homework or leaving feedback, and your file stays private because it never leaves your browser.
