Turbo Dither: High-Performance Browser-Based Image Dithering with Retro Flair

In the world of digital imaging, dithering remains a timeless technique for simulating colors and gradients in limited palettes.
Turbo Dither is a cutting-edge tool that brings professional-grade dithering to your browser. Built with Next.js 15 and React 19, this free application transforms ordinary images into retro masterpieces using authentic algorithms and color schemes from computing history; all without servers, accounts, or compromises on privacy.

Core Features That Set It Apart

Turbo Dither prioritizes speed, usability, and authenticity. Key highlights include:

Blazing-Fast (even though it's not in Rust) Processing: Leveraging Web Workers, image transformations occur in a background thread, ensuring a buttery-smooth UI even on mobile devices.
Diverse Dithering Algorithms:
- Floyd-Steinberg: Error diffusion for natural details.
- Atkinson: Macintosh-inspired brightness and contrast.
- Ordered (Bayer): Pattern-based for classic crosshatch effects.
- Jarvis-Judice-Ninke: Wide-area diffusion for ultra-smooth gradients.
14 Retro Palettes: From CGA's 4 colors to NES's 64, including Game Boy, Commodore 64, Pico-8, and grayscale variants.
Fine-Tuned Controls: Adjust brightness, contrast, saturation, diffusion factor (0.0–2.0), and dither scale for pixel-perfect results.
Privacy and Freedom: 100% client-side—no uploads, account creation, or watermarks.
Interactive Tools: Real-time side-by-side comparisons, progress indicators, and PNG exports with custom names.
