Redact Image
Redact Image permanently removes sensitive data from photos — phone numbers, emails, ID numbers, addresses — with automatic OCR detection or manual selection. Unlike drawing a black box, redacted content is erased from the image data and cannot be recovered. 100% free with batch processing.

Safety & privacy
Your image is sent to our AI server only to run detection and erasure — once processing finishes, the image is deleted from the server, with no storage and no AI training. If you need fully offline processing, our PDF redaction tools run entirely in your browser.
Genuinely free — no limits
KitsyApp is 100% free — no signup, no daily limits, no watermarks. Processing quality is on par with paid tools like Smallpdf or iLovePDF, and your files are processed on your own device instead of someone else's server.
Frequently asked questions
How is this different from drawing a black box?
A black box only covers the visible layer — under some compression or recovery techniques the underlying content can still leak. This tool erases the redacted pixels from the output image data entirely.
What types of information are auto-detected?
Phone numbers, email addresses, ID numbers and other long identifier codes. For anything else, you can manually select regions with a quick drag.
Does it work on handwritten content?
The OCR handles printed text well; handwriting depends on legibility. For handwriting, the most reliable way is manual region selection — always available in the tool.
Are processed images stored?
No. Images exist only during processing and are then deleted from the server. The downloaded file is the only remaining copy.
