Extract PDF Highlights, Comments, and Markups Offline
Managing research summaries or document feedback is simple with our secure offline PDF Annotation Extractor. This utility parses your PDF file locally using browser memory, allowing you to view and download all embedded markups like yellow highlights, sticky comments, custom free-text stamps, ink drawings, strikethroughs, and underlines.
Once extracted, you can filter annotations by their markup type and export the visible list as a formatted spreadsheet (CSV) or a structured plain text document (TXT). Because the entire codebase runs client-side, your privacy is 100% guaranteed. No documents are uploaded to external servers, making this tool compliant for sensitive legal and financial workflows.
Frequently Asked Questions
What types of PDF annotations can this tool extract?
This extractor retrieves standard PDF annotations, including Text (Sticky Notes), Highlights, Underlines, Strikethroughs (StrikeOut), Free Text comments, and Ink drawings.
Does this tool work with scanned PDFs?
Yes, as long as the PDF viewer or editor embeds actual annotations/comments onto the scanned pages. However, if the text comments are flattened directly into the image pixels, they cannot be parsed as annotations.
Can I extract annotations without uploading my PDF to a server?
Absolutely. All parsing and extraction happen inside your browser memory using PDF.js. Your file never travels over the internet, and no remote api calls are executed.
