What is Image Dithering Tool?
Image Dithering Tool applies classic dithering algorithms to any picture directly on a canvas: Floyd-Steinberg and Atkinson error diffusion, or Bayer 4x4 ordered patterns, over 1-bit black-and-white, Game Boy green, and 4-level grayscale palettes, with scale control and instant PNG export - all in your browser.
Key Benefits
- Authentic retro looks from real algorithms, not Instagram-style filters
- Error diffusion preserves shading even in a 2-color palette
- Game Boy palette gives instant hand-held nostalgia
- Scale control trades detail for chunkier, more stylized dots
- Private and instant - rendering and export happen on your device
Common Use Cases
- •Creating retro thumbnails, album art, and lofi social posts
- •Preparing 1-bit graphics for e-ink displays or embedded projects
- •Generating print-style halftone patterns for posters and zines
- •Making game assets that match a limited retro palette
How to Dither an Image
- Choose an image: Pick a PNG, JPEG, GIF, or WebP file - it renders on the canvas immediately.
- Pick algorithm and palette: Try Floyd-Steinberg for smooth shading, Atkinson for a classic Mac feel, or Bayer for print patterns, then switch palettes.
- Scale and download: Adjust the scale for chunkier dots and download the finished PNG.
