Good to know
- Text highlighting needs a PDF with selectable text. On scanned pages, use the Marker instead.
- Annotations are drawn into the pages of the new copy, so they look the same in every PDF viewer but can’t be edited later as separate comments.
- This tool adds marks on top of a page. It doesn’t change or replace the PDF’s existing text.
Supported files
