Image Color Converter

Convert black and white images to color or color images to black and white. High-quality conversion without losing quality.

What is Image Color Conversion?

Image color conversion is the process of transforming images between color and grayscale formats. Converting color images to black and white involves removing color information while preserving luminance, while converting black and white to color (colorization) adds color information to grayscale images.

Our free image color converter allows you to convert color images to black and white or attempt to colorize grayscale images. All processing happens in your browser, ensuring your images never leave your device.

Why Convert Image Colors?

  • Artistic Effect: Create black and white versions for artistic purposes
  • File Size: Grayscale images can be smaller than color images
  • Historical Restoration: Colorize old black and white photos
  • Design Needs: Match design requirements for monochrome displays
  • Print Media: Prepare images for black and white printing

Conversion Methods:

  • Grayscale Conversion: Uses luminance formula for accurate grayscale
  • Colorization: Attempts to add color to black and white images
  • Quality Preservation: Maintains image quality during conversion
  • Format Support: Works with common image formats
