Posterize an image

Posterizing cuts smooth gradients into a handful of flat bands, the way screen-printed posters only have a few inks. In Palette mode the photo is split by brightness into four bands, and each band gets one of your four colors — clashing, high-saturation palettes give the famous pop-art portrait. Levels mode keeps the photo's own colors but limits each channel to 2–8 steps.

How to use it

Upload a photo with a clear face or shape.
Pick Pop art, Neon or Sunset, or switch to Levels.
Change the four colors or the Brightness slider until the bands fall right, then download.

Move Brightness to decide which parts of the face land in which color band.
Make a set: run the same photo with three palettes and post them side by side.
Levels at 3–4 gives a retro video-game look; 6–8 is subtle.

Questions

What does posterize mean?

It reduces an image to a small number of flat colors, removing smooth gradients — like a screen-printed poster with only a few inks.

How do I make Warhol-style pop art?

Use Palette mode with bright, clashing colors (the Pop art preset), then make two or three versions with different palettes and arrange them in a grid.

Can I choose my own colors?

Yes. In Palette mode, tap any of the four swatches — from Darkest to Lightest — and pick a color.
