Frequently Asked Questions

Below you'll find answers to the questions we get asked the most. If your question isn't here, or you need more info, or have feedback, please get in touch.

What is image dithering?

Image dithering is a technique that reduces the number of colors in an image while maintaining visual quality by creating patterns of pixels. This online dithering tool applies error diffusion algorithms to create a retro, artistic effect commonly seen in vintage computer graphics and print media.

Which dithering algorithm should I use?

Floyd-Steinberg is the most popular and balanced algorithm for general use. Stucki provides smoother gradients with less noise. Atkinson creates a distinctive high-contrast look popular in early Macintosh graphics. Burkes offers a middle ground between Floyd-Steinberg and Stucki.

How many colors should I use for dithering?

For a classic retro look, use 2-8 colors. For more detailed images with subtle gradients, use 16-32 colors. Higher values (64-256) create smoother transitions but reduce the dithering effect. Experiment with different values to achieve your desired aesthetic.

What image formats does the dither tool support?

This online image dithering tool supports all common image formats including JPEG, PNG, WEBP, and GIF. The output is always PNG to preserve the dithered patterns without compression artifacts. You can process multiple images at once.

Is this dithering tool free to use?

Yes, this online image dithering tool is completely free with no limitations. All processing happens locally in your browser, so your images are never uploaded to any server. Dither unlimited images for web design, pixel art, or creative projects.
