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
- Select a local file as input.
- Click Run and wait for processing.
- 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.
