Built for journalists, lawyers and anyone publishing a redacted PDF. Runs 100% in your browser — we cannot see your file.
Drop a PDF to check for fake redactions, metadata leaks and active content.
How this works — and why it's private
- Text extraction reveals words underneath filled shapes.
- Metadata inspection surfaces authors, producers and timestamps.
- Catalog inspection flags JavaScript, embedded files and form fields.
- Nothing is uploaded. The audit runs in your browser and stops when you close the tab.
The auditor compares two views of your PDF: the low-level object catalog (via pdf-lib) and the rendered operator list (via pdfjs). Anything one library alone would miss — like text still selectable under drawn-on black boxes — shows up when we cross-reference the two.
