The flat poster recipe
This fixed recipe posterizes to four levels and then calms saturation, producing the flat vector-poster look in one step. Skies become single shapes, faces become clean color zones.
Unlike its adjustable sibling, there is nothing to tune: every image gets the same confident treatment. That consistency suits icon sets, thumbnails and matching social tiles.
Where flat shines
Bold subjects with clear light and shadow simplify best; cluttered low-contrast shots may melt together. High-resolution originals keep edges crisp after flattening.
Use results as tracing bases in vector apps or as stylized placeholders. Save as PNG to keep the flat zones perfectly clean for further design work.
Simple tool, strict privacy
The poster recipe blends its two steps together on your own CPU. No image is staged on a server farm while it waits for a fashionable flattening.
You will find no login walls and no usage counters here. Simplify up to ten images, pocket the downloads, and leave no footprints behind.
Questions
Are my images uploaded when I use this?
No. Everything runs inside your browser on your own device. Your files are never sent to us or to anyone else.
What exactly does this apply?
Every image gets posterize-to-4 plus reduced saturation in one fixed pass, which flattens photos into bold poster shapes with calm colors.
How is this different from Reduce image colors?
Reduce image colors lets you choose 2 to 8 levels per channel; this tool is a fixed recipe with no sliders for a consistent flat look.
Is it free?
Yes. Free to use, with no sign-up, no watermark and no daily limits.
