2Adjust the 'Color Levels' slider to determine how much detail you want to simplify.
3Select a specific 'Posterize Mode' to choose between styles like Comic, Dithered, or Pop Art.

Examples

1. Retro Comic Book Portrait

Graphic Designer

Background

A designer needs to convert a standard portrait into a comic-style illustration for a blog header.

Problem

The original photo has too much detail and realistic shading, which doesn't fit the site's flat design theme.

How to use

Upload the portrait, set the mode to 'Comic Style', and adjust the color levels to 6 for a bold, graphic look.

levels: 6, mode: 'comic'

Outcome

The portrait is transformed into a clean, comic-book-style graphic with distinct color bands and sharp edges.

2. Minimalist Poster Design

Background

A user wants to create a minimalist poster from a landscape photograph.

Problem

The landscape has too many color gradients, making it look cluttered when printed.

How to use

Upload the landscape image, select 'Basic Posterize', and set the levels to 4 to simplify the scene into primary color blocks.

levels: 4, mode: 'basic'

FAQ

What does posterizing an image do?

Posterizing reduces the number of colors in an image, replacing smooth gradients with flat, solid blocks of color to create a stylized, graphic look.

Can I choose the number of colors?

Yes, you can adjust the 'Color Levels' setting between 2 and 16 to control the level of detail reduction.

What file formats are supported?

You can upload JPEG, PNG, and WebP files, and export them in the same formats.

What is the difference between the modes?

Modes like 'Comic' or 'Pop Art' apply specific color palettes and textures to mimic those artistic styles, while 'Basic' focuses purely on color level reduction.

Is there a file size limit?

Yes, the tool supports individual file uploads up to 10MB.
