How Remove PDF annotations works
PDF Remove Annotations strips the annotation layer from a PDF, comments, sticky notes, highlights, underlines, strikethroughs, ink drawings and embedded links, and optionally removes interactive form fields as well. The result is a clean, flat version of the document that shows only the original page content.
Be aware of what is and is not removed: the tool targets the PDF annotation and widget objects; it does not alter the underlying page content stream (text, images, vector graphics). If a highlight colour was "baked" into the page during a previous export, it will remain. For removing hidden document metadata (author name, edit history), use the Office metadata or EXIF tools instead. The annotations are stripped with pdf-lib.
