• Intelligent edge preservation to maintain image clarity
• Automatic color palette generation
• Support for custom color palettes

Color Management

• Adjustable color limit (2-64 colors)
• Smart color quantization for optimal results
• Custom palette support with RGB value input
• Automatic palette generation based on image colors

Advanced Effects

• Adjustable dithering strength (0-100%)
• Edge preservation toggle for detail control
• Floyd-Steinberg dithering algorithm for smooth color transitions
• Transparent background support

How to Use

1. Upload an Image

   • Drag and drop any image file onto the upload area
   • Supported formats include PNG, JPG, and other common image formats

2. Adjust Settings

   • Target Width: Set the desired width of your pixel art
   • Color Limit: Choose how many colors to use in the final image
   • Dithering: Enable/disable and adjust dithering strength
   • Edge Preservation: Toggle edge detection for clearer details

3. Custom Palette (Optional)

   • Enable "Use Current Palette" to work with custom colors
   • Input RGB values in the palette text area
   • Format: [[R, G, B], [R, G, B], ...] where R, G, B are values from 0 to 255

4. Export

   • Click "Download PNG" to save your pixel art
   • The exported image maintains transparency if present

Technical Details

The converter uses advanced image processing techniques including:

• Floyd-Steinberg dithering for color reduction
• Edge detection algorithms for detail preservation
• Intelligent color palette generation using color space analysis
• Perceptual color distance calculations for accurate color matching

Best Practices

• Experiment with different target widths to find the ideal pixel size
• Use edge preservation for images with important details
• Adjust dithering strength based on the desired aesthetic
• Consider using custom palettes for consistent style across multiple images

This tool is ideal for:
