Difference Between Modes

Color Quantization Mode

  • Picks the most common color in each block and fills the entire block with it
  • Groups colors from the original image by blocks, creating unity
  • Results in bold, high-contrast pixel art
  • Fine details become crisp through color grouping

Resize Scaling Mode

  • Shrinks the original image first, then enlarges it back to size
  • Keeps the original colors and gradations relatively intact
  • Creates more natural and smooth pixel art effects
  • Perfect for photos with continuous color transitions

Choosing Block Size

  • 2×2～4×4: Best when you want to keep fine details
  • 6×6～8×8: Great balanced pixel effect (try this first if unsure)
  • 10×10～16×16: For that chunky, old-school retro game look

Use Cases

  • Game Development: Create retro-style characters and backgrounds with ease
  • Web Design: Add 8-bit style icons and decorative elements
  • Art Creation: Perfect for sketching ideas for pixel art projects
  • Social Media: Stand out with unique profile pictures and headers

Technical Features

How Color Quantization Mode Works

This mode examines all the pixels in each block and finds the most frequently used color. Then it fills the entire block with that color, creating a unified and cohesive pixel art effect.

Features and Limitations

  • Creates crisp, clear pixel art since each block has a uniform color
  • Uses colors directly from the original image, so there's no limit on color count (not a fixed palette)
  • Gradations and subtle color changes may be lost in the process

How Resize Scaling Mode Works

The image is first shrunk down according to the selected block size, then enlarged back to the original size. This process creates a natural pixelation effect while preserving the original image's color characteristics.

Features and Limitations

  • Pixel borders are clearly defined because image interpolation is disabled during enlargement
  • Original colors and gradations are relatively well preserved
  • Very fine details may be lost during the shrinking process

Characteristics of Simple Implementation

This tool focuses on ease of use and accessibility with a straightforward approach:

  • Real-time Processing: See results instantly in your browser
  • Source-dependent: Final appearance greatly depends on your original image's characteristics
  • Basic Algorithms: No advanced color correction or dithering processing
  • General Purpose: Features are basic compared to specialized pixel art creation tools

Tips for Best Results

  • For Photos: Try Resize Scaling mode first (gives more natural results)
  • For Illustrations: Color Quantization mode often works great (creates sharp, clear effects)
  • Block Size: Match it to your image complexity (start with smaller blocks for detailed images)
  • Use the Preview: Take advantage of real-time preview to find your perfect size
