Native Mac app · since 2024

Redact sensitive data on Mac, on autopilot

BlurData finds personally identifiable information (PII) on its own in PDFs, scans and screenshots: names, emails, addresses, account numbers and more, without uploading the file. Redact it for good, or pseudonymize it with consistent labels like [PERSON_1] before you send the document to AI.

BlurData on Mac redacting names, amounts and dates in an insurance quotation, with the document preset and detectors panel

Redact or Pseudonymize

Two modes, depending on what happens next

Redact: the data is gone

For documents you send, file or publish. The data you pick is taken out of the file and covered with a bar in the color you choose. Nobody can copy it, search for it or get it back. Redact a PDF →

Dear , your policy of is arranged by .

Pseudonymize: the meaning stays

For documents you want ChatGPT, Claude or a colleague to work on. Every person, address or amount becomes a consistent label on every page, so the text still reads. The key to the real data stays on your Mac. How it works →

Dear [PERSON_1], your policy of [AMOUNT_1] is arranged by [PERSON_2].

Redaction app for Mac, 100% offline

Redact Sensitive Data from Screenshots & PDFs on Mac

8 PII types auto-detected + unlimited custom regex. 100% offline. Works on both screenshots and PDFs, in one app.

Auto-detects 8 PII types (+ regex for anything else)

Emails, names, addresses, IPs, URLs, monetary values, account numbers, license plates — all detected automatically. Add custom regex for internal IDs, JWTs, API keys, ticket numbers — anything you treat as confidential.

Drag & drop any file

Drop any screenshot (JPG, PNG) or PDF into BlurData. Sensitive data is detected and highlighted in seconds — no manual selection needed.

100% offline — data never leaves your Mac

All detection and rendering happens on-device. No cloud upload, no internet required. Acrobat, Foxit and Nitro can find names too, but only with AI features that run in their cloud, so the file is uploaded. BlurData never uploads it, which helps teams that must follow GDPR or HIPAA rules.

Export & batch process

Export images and PDFs with the sensitive text permanently anonymized and removed from the file structure. Batch redact entire folders of files in one pass.

HOW IT WORKS

Automatic PII Detection — No Manual Selection Needed

New · Pseudonymize · September 2026

Anonymize documents for AI, without losing the meaning

Switch from black boxes to consistent labels like [PERSON_1] and [AMOUNT_2]: the same person keeps the same label on every page. Send the copy to ChatGPT or Claude, keep the key on your Mac, read the answer back. 100% offline.

Frequently Asked Questions

Common questions about BlurData's redaction features, privacy, and macOS compatibility.

What sensitive data does BlurData automatically detect and redact?

BlurData automatically detects and redacts emails, names, addresses, IP addresses, URLs, monetary values, account numbers, and license plates. You can define custom regex patterns for any other identifier in screenshots and PDFs. You can also define custom regex patterns to redact any other type of personally identifiable information (PII).

Can BlurData redact PDFs on Mac without Adobe Acrobat?

Yes. BlurData lets you redact PDFs on Mac without Adobe Acrobat. Drag your PDF into the app, review the automatically detected sensitive data, and export a clean redacted version — no Adobe subscription required.

Does BlurData work offline? Is my data private?

Yes, BlurData processes all images and PDFs entirely offline on your Mac. No data is ever uploaded to a server. Your files never leave your Mac, which helps teams that must follow GDPR or HIPAA rules.

How is BlurData different from Preview, CleanShot X or Acrobat?

Preview and CleanShot X make you select and cover each piece of sensitive data by hand. Acrobat, Foxit and Nitro can find names with their AI features, but those run in their cloud, so the document is uploaded. BlurData finds emails, names, addresses and other PII on its own, on your Mac, in PDFs, scans and screenshots.

Does BlurData support batch redaction of multiple files?

Yes. BlurData supports batch PDF and image redaction on Mac. Drop an entire folder of files and BlurData will automatically detect and redact sensitive data across all of them in one pass.

Can BlurData remove QR codes and barcodes from a PDF?

Yes. Turn on Barcodes & QR codes and BlurData finds every QR code and barcode on the page, including Swiss QR-bills, Code 128, PDF417 and Aztec codes, and covers it whatever it encodes, together with the number printed under it. Click the X on a code to keep it visible. It's off by default, and a document preset can switch it on, for example for bank and brokerage statements, where codes often carry the account number and address.

Is there a free trial?

No, but you can try it for 14 days. Every purchase has a 14-day money-back guarantee: use BlurData on your own documents, and if it doesn’t fit them, write to us (or reply to any of our emails) within 14 days of purchase for a full refund.

What macOS version is required?

BlurData requires macOS 13 (Ventura) or later and is optimized for both Intel and Apple Silicon Macs (M1, M2, M3, M4). It supports JPG, PNG and PDF file formats.
