Pixelate image
A fast mosaic pixelator: pick a block size and download the full-resolution result. Your photo stays on your device.
Your pixelated image appears here.
What pixelation actually does
The image is shrunk so each block becomes a single pixel, using high-quality averaging, then scaled back up with nearest-neighbour sampling so every block keeps hard edges. A block size of 12 on a 1200-pixel-wide photo gives a 100-block-wide mosaic.
Want a proper sprite instead of a mosaic? The image to pixel art converter also restricts colours to a palette and gives you a tiny file you can edit in the pixel art maker.
Frequently asked questions
How do I pixelate an image?
Choose the image, then move the block size slider. Each block is filled with the average colour of the pixels it covers. Download the result as a PNG at the original size.
Does pixelation hide faces and text securely?
Not reliably. Large blocks help, but researchers have shown small-block pixelation of text can sometimes be reversed. To hide sensitive information, cover it with a solid box instead.
Is the image uploaded?
No. Everything runs in your browser; the file never leaves your device.
How is this different from converting to pixel art?
Pixelating keeps the full image size and colour count, giving a mosaic effect. The image-to-pixel-art converter creates a truly small image restricted to a palette, which is what sprites and game assets need.
