BlurData - 2026 Pricing, Features, Reviews & Alternatives

BlurData is a desktop application for macOS that performs redaction and pseudonymization of personally identifiable information within PDFs, scanned documents and screenshots. It operates entirely offline without requiring file uploads to external services. It is designed for professionals in legal, healthcare, development and support roles who handle sensitive documents subject to data privacy regulations such as the general data protection regulation and the health insurance portability and accountability act. The offline processing model ensures that confidential information remains on the local device throughout the redaction workflow.

The software automatically identifies a range of built-in data types, including email addresses, personal names, physical addresses, internet protocol addresses, uniform resource locators, monetary values, account numbers with international bank account number support and vehicle license plate numbers. Users can define unlimited custom pattern matching rules for internal case numbers, application programming interface keys, ticket references or proprietary codes. Two processing modes are available. Traditional redaction permanently removes selected data by deleting text from the file structure rather than overlaying it. Pseudonymization replaces sensitive information with consistent labels such as PERSON ONE or AMOUNT TWO across multi-page documents while maintaining a reversible mapping key on the local device.

The interface offers granular control with category-level toggles, individual match removal and freehand selection for arbitrary regions. Double-clicking a word removes all occurrences within the current document or configures a permanent rule for future files. Batch processing enables the simultaneous redaction of entire folders. Optical character recognition with automatic language detection supports fifteen languages including English, German, French, Spanish, Italian, Portuguese, Russian, Ukrainian, Chinese in both simplified and traditional scripts, Japanese, Korean, Vietnamese, Thai and Arabic. Barcode and quick response code detection accommodates common formats such as code one hundred twenty-eight, PDF four one seven, Aztec and Swiss QR bills along with their printed representations.

The application is a self-contained tool that requires no external account or third-party subscriptions and relies on the operating system for text recognition and language processing. Exported files contain truly redacted content so that covered data is removed from the underlying file and cannot be restored. A verification feature scans redacted documents for residual hidden text without transmitting files off the device. The software is compatible with Intel and Apple Silicon architectures and requires macOS Ventura or a more recent release.
