Annotate & highlight a PDF
Highlight, underline, strike through, or drop a note on the page. Every mark is drawn on top, so the text underneath stays exactly as it was — selectable, copyable, and searchable. No network request is made at any point.

These marks are visual, not native annotations. They are drawn on top of the page and can't be edited or removed in another PDF reader — what you see here is what prints. The text underneath is untouched, so it stays selectable and searchable.
