Question 1

What is image dithering?

Accepted Answer

Dithering approximates an image's tones with patterns of dots from a small color set — the retro look of 1-bit Macs, newsprint halftones and Game Boy screens.

Question 2

How do I dither an image online?

Accepted Answer

Open img·dither, drop in a photo (or paste one), pick a pattern like Bayer or halftone, tune the sliders, then download the result as a PNG.

Question 3

Is img·dither free? Does it upload my photos?

Accepted Answer

It's free, with no signup. Photos are processed on a canvas in your own browser and never leave your device.

Question 4

Which dithering patterns are supported?

Accepted Answer

Bayer ordered dithering (4×4 / 8×8), 45° halftone, animated hash noise and crosshatch — each combinable with grayscale, duotone, custom palettes or quantized original color.
