How to Redact Personal Data on a Document?
Secure Upload
Import the scan of your ID card, passport, or confidential file locally.
Draw Black Boxes
Click and drag your cursor to overlay solid, opaque black boxes over sensitive sections.
Permanent Burn
Export the file: the black pixels permanently override and overwrite the underlying information.
Protect Your Identity and Credentials Against Identity Theft
When applying for apartment rentals or registering on web applications, sending raw scans of your ID credentials poses a major security hazard (risk of data breaches). Censoring elements that are not required (such as your place of birth or specific registry numbers) is highly recommended.
Our confidential document anonymizer ensures military-grade security. Unlike editing on a PDF where masking layers remain detachable or removable, our tool redraws the shapes and flattens (burns) the black rectangles directly into the final image matrix. No image processing algorithm will ever be able to recover what has been overridden.
Frequently Asked Questions
Can a hacker remove the black boxes to read the censored text?
No. The process physically replaces the original pixels in that area with pure solid black during the toDataURL() render. The original information is completely destroyed and replaced, rendering any reverse-engineering attempts impossible.
