How posterization changes an image
Posterization reduces the number of values available in each RGB channel. Smooth gradients become distinct bands, and complex photos take on a graphic, screen-print, or retro-poster character.
Use fewer levels for a dramatic style and more levels for controlled simplification. Strong posterization can emphasize compression noise, so starting with a clean, reasonably sized source image produces better results.
Frequently asked questions
What does posterize mean in image editing?
Posterizing reduces the number of color or tonal levels, creating visible bands and flatter areas of color.
How many posterize levels should I use?
Try 4 to 8 levels for a recognizable poster effect. Lower values are bolder, while higher values preserve detail.
Can I make the effect less intense?
Yes. Lower the strength slider to blend the posterized result with the original image.
Does this tool upload my image?
No. Processing and export happen locally in your browser.
