Everything runs inside your browser
RedactOffline is the only redaction tool where your files never leave your device. No server connection, no cloud storage, no data collection.
100% Offline, Zero File Transmission
Your document never leaves your device, not when loading, not during processing, not on export. RedactOffline runs entirely via WebAssembly in your browser tab. No server, no cloud, no data leak risk.
Automatic PII Detection
The auto-detection engine identifies full names, email addresses, phone numbers, postal addresses, social security numbers, dates of birth, bank account numbers (IBAN) and license plates. Sensitive zones are highlighted instantly.
Precise Manual Redaction
Draw pixel-perfect redaction boxes over any area of your document. Perfect for information the auto-detector may miss: confidential logos, stamps, handwritten annotations, custom fields.
Multi-Format: PDF, PNG, JPEG, WebP
Import multi-page PDFs or image files (document photos, scans). Rendering faithfully mirrors the original page by page. Maximum file size: 50 MB.
Permanently Redacted PDF Export
The exported PDF contains solid black permanent regions, redacted content is not just visually hidden, it is removed from the PDF data stream. It cannot be recovered by selecting text or inspecting metadata.
Batch Processing (Premium)
Import and redact multiple documents simultaneously. Ideal for legal teams, HR departments, or accounting teams handling large volumes of confidential documents.
Under the Hood, Privacy by Design
WebAssembly (WASM) Engine
All document processing and OCR run directly in the browser thread via WASM, native performance, zero backend required.
Built-in OCR
Scanned PDFs (image-based) are analyzed by an embedded OCR engine. Personal data is detected even in digitized documents.
Custom Patterns
Define your own regular expressions to detect formats specific to your industry: case numbers, client codes, internal references.
GDPR / HIPAA / CCPA Compliance Ready
By processing data locally, you automatically fulfill data minimization and transfer restriction obligations imposed by GDPR, HIPAA, and CCPA.
