About this tool

Mark up a PDF with a pen, highlighter or text, and erase mistakes. Your marks are baked into a new PDF in your browser, so the file is never uploaded.

How to annotate a PDF online

  1. Choose a PDF and select a page.
  2. Draw, highlight or add text, using the eraser to fix mistakes.
  3. Save the annotated PDF.

Frequently asked questions

Can I edit the existing text of a PDF?

No. This tool adds marks on top of the pages. It does not rewrite the original text.

Are my annotations permanent?

Yes, they are saved into the new PDF as part of the page, so keep the original if you want an unmarked copy.

Is the PDF uploaded?

No. Annotating happens in your browser.
