How this works
Your browser applies a classic error-diffusion dithering algorithm (Floyd–Steinberg or Atkinson) directly to the image's pixels, reducing it to a limited color palette while spreading the rounding error to neighboring pixels to preserve the illusion of detail — no file is uploaded.
Common use cases
- Create a retro, dithered version of a photo for a creative project
- Convert a photo into a reduced-color, pixel-art style image
- Prepare an image for a low-color display or printer
Frequently asked questions
Is this dithering tool free?
Yes. It is completely free, with no signup and no watermark.
Is my photo uploaded anywhere?
No. Dithering happens entirely in your browser. Nothing is sent to Inqita or stored.
What's the difference between Floyd–Steinberg and Atkinson?
Floyd–Steinberg diffuses more of the rounding error to neighboring pixels for a smoother look; Atkinson diffuses less, giving a higher-contrast, more classic Mac-style look.
What does the color level setting do?
It controls how many shades each color channel is reduced to — 2 levels per channel gives a stark black-and-white look, higher levels keep more of the original color range.
