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. • Redact several PDFs in a row: drop them all and go one by one. • Works with any PDF, nothing else to install, no sign-up. ⭐ SMART DETECTION (Pro — your first detection is free) Finds and marks for you, in one click: • Emails and phone numbers (US and international formats) • IBAN bank accounts and bank cards (checksum + Luhn validation) • US Social Security numbers, Spanish IDs (DNI/NIE/CIF) and more • Or type any word or number and redact every single occurrence 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, forever. Your first auto-detection is free too — after that it's a one-time purchase: buy once, yours forever, valid across all your browsers.
