Frequently Asked Questions
What makes this Pixel Art Converter different?
This Pixel Art Converter uses professional-grade algorithms including median-cut quantization, error diffusion dithering, and ordered dithering. Unlike basic converters, it offers advanced controls for grid size, color palette reduction, and dithering modes to achieve authentic 8-bit and 16-bit aesthetics.
Best settings for different projects?
Game Sprites: Use 8-16 colors, small grid size (3-5), no dithering for clean results perfect for 2D games.
Portrait Art: 24-32 colors with Error Diffusion dithering creates smooth gradients while maintaining the retro aesthetic.
Retro Graphics: Large grid size (8-12), 8 colors maximum, Ordered dithering for authentic vintage output.
Logo Design: No dithering, 16 colors, medium grid for sharp, clean results ideal for branding.
Is there a file size limit?
Since processing happens in your browser, very large images (>4000px) may slow down or crash the page. For best results, use images under 2000px on the longest edge.
Commercial Pixel Art Converter usage?
All pixel art created with this Pixel Art Converter is 100% royalty-free for commercial use. Many indie game developers, digital artists, and design agencies use this tool for client projects, game assets, and commercial artwork without restrictions or watermarks.
Why does it take a while to convert?
Complex algorithms like median-cut color quantization and dithering require significant computation. Everything runs locally in your browser without server uploads, so processing time depends on your device's performance.
