⚡ Try with a sample photo
Blur or black-box sensitive parts of any photo — faces, license plates, addresses, credit cards, screen content, ID numbers — before you share or post. Runs in your browser, which matters: redaction tools online routinely upload the exact photos people are trying to protect. This one does not. Pick a region, apply Gaussian blur, mosaic, or a solid black box, and export.
What redaction can and cannot do
A strong redaction removes information permanently from the exported image. Gaussian blur and pixelation, at sufficient strength, are unrecoverable — there is no original data left in the image for anyone to enhance back. A solid black box is the strongest and is the right choice for legal documents, ID numbers, and anything you need to clearly demonstrate is covered. A light blur that still lets you make out letters is not real redaction and has been broken many times in news stories. When in doubt, use a black box.
Faces, plates, screens, and documents
Faces — moderate pixelation (block size 20-30px) or heavy Gaussian blur. For real anonymity, pair with cropping away identifying clothing and context. License plates — pixelate or black-box; plates are the single most identifying element in a car photo. Screens and monitors — black-box the area showing sensitive content; blur is often too weak against zoom. Document text — black-box, always. Also strip the photo's EXIF metadata before sharing, because GPS coordinates in a redacted ID photo still give away where you took it.
The right redaction workflow
A good flow: take the photo, strip EXIF first so location metadata is gone, redact the visible sensitive areas here, then compress for upload. The EXIF step is the one most people skip — a redacted ID photo with GPS at your home address is barely redacted at all. For photos that include a person you want to fully remove rather than blur, the magic eraser is the right tool.
