Redact and Anonymize Text in PDFs and Images on macOS

Looking for a secure and efficient PDF anonymization tool for Mac? BlurData is a powerful macOS application designed to automatically redact or blur private information from both images and PDF documents. Whether you're preparing files for public sharing, internal reviews, or GDPR compliance, BlurData helps you protect sensitive data like names, emails, IP addresses, and financial records — all in seconds.

Unlike many cloud-based redaction tools, BlurData runs entirely offline on your Mac. That means your documents and screenshots never leave your computer, ensuring maximum data confidentiality. This makes it especially appealing for legal teams, HR departments, IT administrators, and freelancers who deal with personal or client data.

Custom Regex Redaction: Your Patterns, Your Rules

The latest version of BlurData introduces a game-changing feature: custom regular expression (regex) support. Now, you can define your own patterns to identify and blur specific strings of text. Need to hide a customer ID like “CUST-12345” or internal ticket codes? Simply input the regex, and BlurData will automatically scan your images or PDF text for matches.

This level of customization turns BlurData into a flexible privacy software solution for Mac users who want full control over what gets redacted. It’s ideal for developers, compliance officers, and anyone handling recurring formats of sensitive data.

Batch Redaction Across Multiple Files

If you need to process more than one file, you’re in luck. BlurData supports batch redaction, letting you apply your regex rules across entire folders of screenshots or multi-page PDFs. Whether you’re preparing a data dump, sharing training material, or cleaning up support documentation, this feature can save hours of manual work.

  • Fast and automatic detection of personal or sensitive information
  • User-defined regex patterns to catch custom formats and internal codes
  • Batch redaction support for processing multiple PDFs or images at once
  • 100% offline privacy tool — no internet connection or server uploads needed
  • Only available via direct download from blurdata.app (not on the Mac App Store)

BlurData is built for people who need efficient, precise, and private redaction tools on macOS. With its regex detection and batch processing capabilities, it fills the gap for professionals who need more than just a simple blur tool. Download it today and take full control over your data visibility.
