Posterizing reduces the number of color levels in a photo, replacing smooth gradients with bold, flat bands of color — a graphic, screen-printed look. It's useful for poster designs, vector-style illustrations and simplifying an image into clean shapes.

How to apply the posterize effect

  1. Open your photo — drag it onto the tool above, choose a file, or paste from your clipboard.
  2. The posterize effect is already selected. Switch to any other effect from the grid if you'd like to compare.
  3. Drag the intensity slider to dial the look in, watching the live preview update as you go.
  4. Choose a format and click Download to save the result to your device.

Tips & ideas

More intensity means fewer color levels and a chunkier, more abstract result. It pairs naturally with the pop-art and sketch effects.

What does posterize mean?

Posterize reduces the continuous tones of an image to a smaller number of distinct levels. Instead of a smooth gradient from light to dark you get a few flat steps, which gives a bold, poster-like appearance.

Where is my image processed?
