Blur or pixelate part of an image
Blur, pixelate or black out a face, an address or a card number. The pixels are destroyed, not covered.

How it works
This is the one job where uploading the file defeats the entire purpose. You are hiding something — a face, a home address, a bank card, a colleague's screen in the background of a photo — and the usual advice is to send the unredacted original to a stranger's server first. Here the original never leaves your device, and the hidden pixels are genuinely gone from the file you save.
The pixels are destroyed, not covered
This matters more than it sounds. Drawing a black box in a document editor often leaves the original image underneath, recoverable by anyone who knows where to look — which is how several well-publicised leaks happened. Here the selected pixels are overwritten in the image data itself. There is nothing underneath to recover.
Pixelate, blur or block
A solid block is the safest and the most obvious. Pixelation is the familiar look and, at a strong setting, is not reversible in any practical sense. Blur looks the tidiest but is the weakest of the three: a light blur over a small, predictable thing like a number plate can sometimes be partially reconstructed, so use a strong setting or pick one of the other two.
Choosing a strength
Higher strength means bigger blocks or a heavier blur. For anything that matters — faces, addresses, account numbers — use a high strength, or use the solid block. For merely tidying a background, a light setting looks better.
Metadata is a separate problem
Hiding something in the picture does not remove the location and device details stored in the file's metadata. If the photo might reveal where it was taken, run it through the metadata remover as well.
Blur or pixelate part of an image — questions
Can the hidden part be recovered?
Not from the saved file. The pixels are overwritten in the image data rather than covered by an overlay.
Which method is safest?
A solid block, then strong pixelation. Light blur is the weakest and can sometimes be partially reversed on small, predictable subjects.
Is my photo uploaded?
No. It is decoded, edited and re-encoded entirely in your browser.
Does this remove the photo's location data?
No — that is stored separately in the file's metadata. Use the metadata remover for that.
