A browser-based checker that tests whether PDF redactions actually hide text, leftover originals, and metadata.

For
People publishing or submitting sensitive PDF documents
Worth noticing
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.
