Frequently Asked Questions

What is image dithering?

Dithering is a technique used to create the illusion of color depth in images with a limited color palette. By placing pixels of different colors close together, the human eye perceives them as a new color.

Is it safe to process my private photos?

Yes. Like all our tools, the PNG Ditherer runs 100% locally in your browser. Your images are never uploaded to our servers, ensuring total privacy.

Which dithering method should I use?

Floyd-Steinberg is the most common and provides good results for most images. Atkinson is great for high-contrast retro looks, while Stucki often produces sharper results.
