How to annotate a PDF

  1. Drop your PDF into the box above.
  2. Choose Highlight, Underline or Strikethrough and select text, or use the pen, shapes and notes.
  3. Press Save annotated PDF.

Your markup is saved as standard PDF annotations: highlights, ink, rectangles, ellipses, lines and comments. That means Adobe Acrobat, Preview, Chrome, Edge and most other readers show them, and people can review or remove them.

Questions

Will others see my highlights and notes?

Yes. They're saved as standard PDF annotations, which every common PDF reader shows. Notes appear as a comment icon that opens when clicked.

Can I highlight a scanned PDF?

Scanned pages have no text to select, so switch to Draw a box and drag over the area instead. Or run OCR PDF first to make the text selectable.

What does "Draw markup into the page" do?

It paints highlights, drawings and shapes straight onto the page instead of saving them as annotations, for apps that hide annotations. They can't be removed later. Notes always stay as comments.

Are my files uploaded anywhere?

No. PaperSwoop reads your files with your browser and builds the result on your device. You can even turn off your internet after the page loads and it still works.
