Pixelate Region
Pixelate a rectangular area of an image to obscure faces, license plates, addresses, or other sensitive details.
About Pixelate Region
Pixelate Region blocks out part of a photo or screenshot — a face, a license plate, an address, an account number — by replacing a rectangle you choose with chunky averaged blocks. It's the fastest way to hide sensitive details before sharing a screenshot. The pixelation runs entirely in your browser, which is exactly what you want for an image sensitive enough to need redacting.

Frequently asked questions
How do I choose what gets pixelated?
Set the rectangle's x, y, width, and height in pixels. Leaving width and height at 0 pixelates the whole image.
Can pixelation be reversed?
Each block replaces its pixels with their average color, so the detail inside is genuinely discarded — there's no hidden layer to recover. Bigger block sizes discard more.
What block size should I use?
The default (16 px) hides text and faces at typical screenshot sizes. For high-resolution photos or extra caution, go bigger — 32 or 64.
Does the image leave my device?
No. The whole point is redacting sensitive content, so the tool runs entirely in your browser with no upload.
What about the photo's hidden metadata?
Pixelation only changes pixels. Run Strip EXIF Metadata afterwards to also remove location and device info embedded in the file.
