- It checks hidden text, unreferenced original objects, and metadata or embedded files.
Field notes
The checker separates visual concealment from actual removal, including a less obvious case where deleted content remains in unreferenced PDF objects. It also treats metadata and embedded files as a separate disclosure channel, naming author information, original filenames, and saved paths as possible exposures. The homepage says processing remains in the browser and provides links to reported incidents and a three-step self-check guide.
