I built a free image-to-pixel-art converter that runs 100% in the browser

Short summary

A developer built a free, browser-based pixel-art converter using median-cut color quantization, entirely client-side with no backend. It handles downsampling, palette mapping against retro palettes (Game Boy, NES, PICO-8), and sharp nearest-neighbor upscaling—with no watermarks and images never leaving your device. Technical optimizations like RGB caching and weighted distance metrics deliver fast, accurate conversion.

• •Free browser tool converts images to pixel art with zero backend or watermarks
• •Uses median-cut quantization and supports retro palettes (Game Boy, NES, PICO-8)
• •Client-side only—all processing happens locally with no image uploads
