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.
