About this tool
Mark up a PDF in your browser. Pick a page, choose highlight, rectangle, or text, click and drag, then download a new annotated PDF. The original page contents are untouched — your annotations are added on top.
Frequently asked questions
What kinds of annotations are supported?
Highlights (translucent color over a region), rectangles (outline only), and free text. Click-and-drag to draw, then save the annotated PDF.
Are my annotations editable later?
Annotations are flattened into the page so they survive every viewer, but they cannot be removed afterwards. Keep your original file if you might need to redo edits.
