Pixelate Image Online Free — Blur Faces & Areas, No Upload

How to pixelate an image (3 steps)

1. Pick your image. Load any photo — it is processed only on your device.
2. Set the pixel size. Small blocks (4–8 px) give a retro mosaic; large blocks (24–60 px) anonymize faces and license plates completely. The preview updates live as you drag.
3. Download. Save the pixelated image at its original dimensions.

Why this is the right way to anonymize

Before posting a screenshot that contains a name, address, or face, pixelation is the fastest way to redact it — and a blur is not enough, because modern de-blurring tools can recover some detail. True pixelation destroys information permanently: the image is downsampled to a coarse grid and scaled back up with smoothing disabled, so the original pixels simply do not exist in the output. And because it runs locally, the photo with the sensitive details never crosses your network.

FAQ

• Can someone de-pixelate my photo? No — unlike blur, pixelation discards the high-frequency detail permanently.
• Does the file stay the same size? Dimensions stay identical; as a PNG the file may shrink because flat blocks compress well.
• Is the photo uploaded? No — all processing is in-browser.
