→Frequently asked questions
- What is ordered dithering?
- It uses a repeating Bayer threshold pattern to approximate extra tones with a small, deliberate pixel pattern.
- How is this different from Color Reducer?
- Color Reducer chooses a compact palette; dithering distributes the remaining color error as a visible retro pattern.
- What settings work best?
- Start with four color levels and a pattern size of two, then increase either value for a gentler result.
- What file formats can I export?
- You can export as PNG, JPEG, WebP, TIFF, BMP, or HEIC.
- Is this tool free to use?
- Yes — completely free, no account needed. Your images are processed entirely in your browser and never uploaded to a server. Downloads have no watermarks.
