Transform color photographs into striking black and white images. Xonvert's grayscale converter uses perceptual luminance weighting (based on how the human eye perceives brightness) to create natural-looking monochrome results. Perfect for artistic photography, document scanning optimization, and reducing visual distractions in images.

Key Features

  • Perceptual luminance-based conversion (BT.601/BT.709)
  • Natural-looking grayscale results
  • Preserves contrast and tonal range
  • Works with JPG, PNG, WebP, and more
  • Instant processing with no quality loss
  • Output in any supported format

Frequently Asked Questions

Is grayscale the same as desaturating?
Xonvert uses luminance-based conversion, which weighs green more heavily (as the human eye is most sensitive to green), producing more natural results than simple desaturation.
Can I adjust the grayscale intensity?
The grayscale conversion is full (color to black and white). For partial desaturation, use the Saturation tool.
