常见问题
What is the Grayscale Converter?
This tool converts colored images into grayscale (black and white) by removing color information while retaining luminance data.
What conversion algorithms are available?
You can choose between Average, Luma (Rec. 601 & Rec. 709), Desaturation, and Single Channel (Red, Green, or Blue) extraction methods.
What is the difference between Average and Luma methods?
The Average method simply calculates (R+G+B)/3 for every pixel. The Luma method applies specific weights to mimic human eye sensitivity (0.299R + 0.587G + 0.114B), resulting in a more natural look.
Which algorithm should I use for printing?
For printing, the 'Desaturation' or 'Luma' methods are generally preferred as they maintain better contrast and tonal range than the simple Average method.
Does this tool modify the original file?
No. The tool processes a copy of the image you upload. Your original image remains untouched on your device.
Why would I use Single Channel extraction?
Single Channel extraction converts the image based solely on the intensity of Red, Green, or Blue pixels. This is useful for analyzing specific color data or creating artistic high-contrast effects.
