Pixelate Image

Pixelate Image Online

Turn a photo into big, chunky pixels. Use it to create a retro 8-bit / pixel-art look, to make a mosaic background, or to hide details in parts of an image. Load an image, set the pixel size and download the result. Everything happens in your browser.

Whole image or selected areas

With no selection, the entire picture is pixelated. Drag rectangles on the original image to pixelate only those areas — faces, signs, screens, number plates — while the rest stays sharp. Add as many areas as you like and clear them with one click.

How pixelation works

The image is divided into a grid of square blocks. For every block the tool computes the average color of all pixels inside it and fills the block with that color. Transparent pixels are weighted by their alpha, so pixelating a logo with a transparent background does not create dark halos around the edges. Blocks at the right and bottom border are simply smaller when the image size is not a multiple of the pixel size.

Ideas

• Pixel-art avatars and game sprites: pixelate a portrait at a large size, then reduce colors.
• Spoiler images: pixelate a screenshot to tease without revealing details.
• Backgrounds: a heavily pixelated photo makes a colorful, abstract background for slides and wallpapers.
• Privacy: quick anonymization of faces and plates. For text like passwords, a solid bar is safer — see the Censored Image tool.
