About this tool

Find credit card candidates in PDF: Scan extractable PDF text for credit card-like numbers and mark Luhn-valid matches as high confidence.

Use cases

  • Review invoices before sending them to vendors.
  • Check payment receipts for card-like numbers.
  • Use a local candidate report before redaction.

How to use it

  1. Select a local file as input.
  2. Click Run and wait for processing.
  3. Download or copy the output.

Notes

  • Runs locally in your browser; files are not uploaded to MakeTool servers.
  • Local-only processing with no network required.
  • PDF redaction depends on extractable text; scanned or encrypted PDFs fail safely.
  • The redacted copy rebuilds pages so old text is not recoverable by copy, search, or text extraction.
