Redact Personal Information from Images — Free, Private, No Upload

Your images contain more personal data than you think. Names in headers, phone numbers in footers, email addresses in screenshots, account numbers on statements. Every time you share an unredacted image, that data goes with it.

Image Anonymizer scans your images using OCR, detects personal information automatically, and redacts it — all inside your browser. Nothing gets uploaded. Nothing gets stored. Nothing leaves your device.

What Gets Detected and Redacted

  • Names — Full names, first/last names found in text
  • Email addresses — Any email pattern in the image
  • Phone numbers — Local and international formats
  • Dates — Birth dates, document dates, expiry dates
  • ID numbers — Social security, passport, driver's license numbers
  • Addresses — Street addresses, postal codes, city names
  • Custom terms — Type any specific word or number you want redacted

How It Works

  1. Upload your image — Drag and drop, paste from clipboard, or select a file. Supports JPG, PNG, and other common formats.
  2. Enter terms to redact — Type the names, numbers, or words you want removed. Or let the automatic detection find them.
  3. Choose redaction style — Blur or black box. Both make the text completely unreadable.
  4. Download the clean image — Your redacted image is ready in seconds. The original is never modified.

Frequently Asked Questions

Is my image uploaded to a server?

What file types are supported?

What languages does it support?

English and German text recognition. More languages coming based on user demand.

Is it really free?

Yes. No limits, no watermarks, no account required.
