You can convert an image to grayscale (black and white). This is useful for consistent thumbnail styling, setting a specific mood, or emphasizing content through color contrast.
grayscale
Description
Converts the image to grayscale (black and white).
Format
?grayscale=true
Supported values
true | false
Applied only when true (not set or false → no effect)
Examples
?grayscale=true
흑백으로 변환
?width=600&format=webp&grayscale=true
600px 리사이즈 + WebP 변환 + 흑백
Using with other options
grayscale works seamlessly with other transformation options such as format and width.
Mixing the color and grayscale versions can help create an effect where only the content you want to highlight remains in color.
