Use Pixelate Image

Create a block-pixel effect with an adjustable block size and a PNG download. Choose a local image and adjust the settings before processing.

Behavior and limits

The image is reduced and enlarged with nearest-neighbor sampling. Block size controls the coarse detail. Pixelation is a visual effect and should be reviewed carefully before relying on it to obscure sensitive content.

Expected behavior for the example

Choose an image, apply the settings and download a fresh PNG. The source file stays unchanged.

Check important output in the application that will consume it. Use the tool directory to find related formats and tasks.
