TACHADO — Redact your PDFs locally

Redact IDs, IBAN, phones and more in your PDFs by truly removing the text. All on your device: your files are never uploaded.

What's redacted stays redacted. TACHADO permanently censors the sensitive data in your PDFs — and your files never leave your computer. Unlike online PDF tools that upload your document to a server, everything is processed inside your browser. Zero uploads. Zero trace. ⚠️ THE PROBLEM WITH "FREE" TOOLS Most just draw a black box ON TOP of the text… but the text is still underneath. Anyone can recover it with copy-paste. Contracts, payslips and reports have leaked exactly this way. TACHADO doesn't: it rasterizes the area and DELETES the content. What you redact is gone. ✅ WHAT YOU CAN DO • Mark any data with a box and download the already-redacted PDF. • The text under the black area is erased: it can't be copied, searched or recovered. • Works with any PDF, nothing else to install, no sign-up. ⭐ AUTO-DETECTION (Pro) Finds and marks for you, in one click: • Emails • Phone numbers (any format) • IBAN bank accounts (international checksum validation) • Bank cards (Luhn validation) • Spanish IDs (DNI/NIE/CIF) and Social Security numbers You review what's proposed and decide what gets redacted. Official validation avoids false positives — it only marks real data, not just any number. 🔒 REAL PRIVACY • 100% local processing. Your PDFs are never uploaded. • We collect no data. No analytics, no tracking, no accounts. • Even the fonts ship inside the extension: no external servers are called. 👩‍⚖️ BUILT FOR PEOPLE WHO HANDLE SENSITIVE DATA Law firms, HR, accountants, healthcare, public admin… anyone who needs to share a document without exposing personal data and stay GDPR-compliant. 💳 PRICE The basics (mark and redact) are free. Auto-detection is a one-time purchase: buy once, yours forever, valid across all your browsers.
