Posterize photo online
Select a picture on your computer or phone, specify the number of posterized colors and then click OK. Other settings are installed by default.
Posterization serves to reduce the number of tones (colors) of the image, for example, when creating a GIF or PNG picture consisting of 256 colors or less, and is also used as an artistic effect in photography.
With this online tool you can posterize any image in JPG format and up to 20 megapixels.
On this website there is a similar online tool: dithering or limiting the number of colors.
The original image is not changed. You will get other processed image.
