Photo checks
These basic checks measure image size, tones and small contrast changes. Please check focus, faces and likeness yourself. They do not guarantee a finished painting or a print result.
Compare simplified colors
See how your crop looks with a smaller screen palette. Try 24, 36 and 48 colors to compare which details remain visible.
This is a color simplification only. It does not create numbered painting regions and does not match a factory's paint palette. More colors do not automatically make a photo easier to paint.
Your images stay in this tab. Download your results before leaving or refreshing the page.
These free tools work with any paint by numbers kit. For a new project, explore our custom photo kit.
