What is dithering and how does it work?
Dithering is a technique that uses patterns of dots to simulate additional colors and shades in images with limited color palettes. It was commonly used in early computer graphics and printing to create the illusion of more colors than were actually available. The tool lets you experiment with different dithering algorithms and styles.
Which dithering styles are available in our generator?
Our dither generator offers 6 powerful algorithms: Bayer dithering for traditional error-diffusion effects, Dotted/Halftone for classic print-style patterns, Custom Pattern dithering for unique artistic effects, Retro dithering for authentic vintage computer aesthetics, Pixelation for 8-bit style artwork, and ASCII art conversion for text-based image representations. Each style can be fine-tuned to achieve your desired artistic effect.
What is a dither effect?
Dithering is a technique that simulates extra colors and gradients using carefully placed pixels. It produces a distinctive retro, 8-bit or print-press look popular in posters, album art and modern brand design.
Which dithering algorithms does the tool support?
The dither generator supports popular algorithms such as Floyd-Steinberg, ordered (Bayer) dithering and halftone dots, each producing a different retro aesthetic.
Can I upload my own image?
Yes. You can drag and drop any JPG or PNG image into the dither generator and preview the effect in real time as you adjust intensity, color depth and pattern.
Is the dither generator free?
Yes. The dither generator is completely free to use in your browser, with no signup required, and you can export your dithered image as high-quality PNG.
