Frequently Asked Questions
Q: How does grayscale conversion work?
A: We use the industry-standard luminance formula that weighs red, green, and blue channels according to human eye sensitivity: 29.9% red, 58.7% green, and 11.4% blue.
Q: Will the image size change?
A: No, the image dimensions and file size remain essentially the same. Only the color information is converted to grayscale values.
Q: Can I convert back to color?
A: No, grayscale conversion removes color information permanently. We recommend keeping a backup of your original color image.

Frequently Asked Questions
Can I convert back to color after making an image grayscale?
No. Converting to grayscale permanently removes color information. Keep the original color image if you may need it later.
Will grayscale reduce file size?
The pixel dimensions stay the same, but grayscale images contain less color data. Saving as a single-channel format can reduce file size.
Is grayscale the same as black and white?
Grayscale includes all shades from white to black. The "Black & White" tool in FlexKit uses a threshold to produce pure black or pure white pixels only.
What is the difference between grayscale and desaturating in Photoshop?
The grayscale conversion uses a luminance-weighted formula (similar to desaturate). The result is nearly identical.
