A lot of PDFs that look “redacted” still leak information through hidden text layers, metadata, or invisible characters. This tool checks for that. React PDF Audit runs entirely client-side and scans a PDF to see whether anything is still extractable before you share it. It doesn’t redact files or upload them anywhere — it just tells you if something was missed. It’s meant as a quick sanity check for anyone dealing with sensitive PDFs who wants to know whether a redaction actually worked.
