Redact sensitive data from photos and PDFs — automatically, in seconds. Point BlurData at a photo, a scan or a multi-page PDF: on-device AI detects names and surnames, email addresses, IBAN and account numbers, amounts, home addresses, URLs, IP addresses and license plates. Everything gets covered with clean redaction boxes, ready to share safely. TRUE PDF REDACTION Most apps just draw a box on top. BlurData can remove the hidden text from the PDF file itself: what you redact cannot be selected, copied or recovered — while the rest of the document stays real, searchable text. Or flatten every page to images for maximum compatibility. BUILT FOR REAL DOCUMENTS • One-tap presets for payslips, invoices and bank statements (Italian, German, US) plus community presets • Custom patterns: hide any word, sequential IDs like Bates numbers, or full regular expressions • Smart name detection: multi-language first-name dictionary, honorifics (Mr., Dr., Sig.), middle initials and surname propagation • Draw to redact stamps, signatures and anything OCR can't read • Multi-page PDFs: every page scanned and redacted automatically • Double-tap any word in the preview to hide it everywhere • 7 redaction colors, pinch-to-zoom inspection, hold-to-reveal comparison PRIVATE BY DESIGN All processing happens on your iPhone and iPad. Your documents never leave the device — no uploads, no cloud, no account required. FREE TO TRY, PRO TO EXPORT Load documents, run detection and preview redactions for free. Unlock PRO (or grab a one-time Saves Pack) to save unlimited pages to Photos and export protected PDFs.
