Effect Preview

How it works

Downscales the image to create blocks, then scales back up using nearest-neighbor interpolation. Preview uses canvas rendering for instant feedback.

What This Tool Does

Pixelate images to blur out sensitive information like faces, license plates, or personal data. Also great for creating retro pixel art effects. Control the pixel block size for fine or coarse pixelation.
