Posterization collapses the smooth color gradients of a photo into a small number of discrete tones, producing the flat, graphic look used in pop-art and poster design.

よくある質問 (FAQ)

Does this permanently change my original file?

No. The effect is applied to a copy rendered in your browser. Your original image on disk is never touched — you download a new file with the effect applied.

Can I adjust the intensity before downloading?

Yes. Every slider updates the preview in real time, so you can fine-tune the effect before exporting the final image.

What format is the downloaded file?

PNG, to preserve full quality and, where relevant, transparency.
