The extractor uses PDF.js to inspect both the annotation layer and selectable text. This matters because a document may contain a clickable link whose visible label is not a URL, or it may print a web address without making it clickable.
Every result stays inert. The tool lists targets for review but does not visit websites, send email, run PDF actions, or change the source file. Export the audit as CSV when you need to check a report, hand links to an editor, or compare destinations in a spreadsheet.
