Markup PDF — Highlight, Note and Draw on Your Device
While reviewing a document, highlight the important parts with a marker, draw freely with a felt pen, box things in, draw arrows and add text notes. The highlighter and marker are semi-transparent, so the text underneath stays readable. Pick different colors and thicknesses, and work across multiple pages. Everything happens in your browser (on your device) — your file is NEVER uploaded. Download the annotated PDF.
Frequently Asked Questions
How do I highlight text in a PDF?
Upload the PDF, pick the 'Marker' tool, choose a color and drag over the text. The marker is semi-transparent, so the underlying text stays readable. Click 'Apply & download' to get the annotated PDF.
Does drawing over text erase it?
No. Annotations are drawn on top of the PDF; existing text is never removed or changed. The highlighter/marker is semi-transparent, so the text below stays visible.
Does my file get uploaded?
No. All annotating happens in your browser (on your device); the PDF is never uploaded. It's 100% private and needs no sign-up.
Which tools are there besides the highlighter?
Alongside the highlighter, there's a freehand pen, a rectangle box, arrow/line, and a text/note tool.
Can I undo my annotations?
Yes. You can undo or delete annotations before applying; the original file stays unchanged until you download the final PDF.
