What is Atkinson Dithering?

Atkinson dithering was the algorithm behind the classic 1-bit graphics of early Macintosh computers. It converts photos i nto beautiful two-tone pixel patterns, producing images with a distinctive vintage charm and remarkably small file sizes.

Features

• 7 retro-tech color palettes: Terminal Green, Amber Monitor, Original Macintosh, Game Boy, Apple II Green, White Phospho r, and classic black & white
• 5 iconic frames inspired by computing history: MacPaint, Classic Mac window, Terminal, White Frame, and frameless
• Adjustable brightness control
• Rounded corner option

Color Palettes

Go beyond black and white. Choose from color palettes inspired by legendary displays — the green glow of VT100 terminals, the warm amber of IBM monitors, the creamy screen of the original Macintosh, and more.

Retro Frames

Wrap your dithered photos in frames inspired by classic software. The MacPaint frame features pixel-perfect tool palettes and menu bars, just like Bill Atkinson's legendary paint program. The Classic Mac frame recreates the iconic window chrome of early Macintosh.
