Description
​Brightness​
bright=X | f=bright:X
adjusts the brightness of the image
​Contrast​
contrast=X | f=contrast:X
adjusts the contrast of the image
​Saturate​
saturate=X | f=saturate:X
adjusts the saturation of the image
​Grayscale​
gray=1 | f=gray | 
grey=1 | f=grey
converts the image to a black and white one
​Color overlay​
colorize=X | colourise=X
applies a color overlay
​Pixelate​
pixelate=X | f=pixelate:X | 
pixellate=X | f=pixellate:X
pixelates the image into X-pixel-sized blocks
​Blur​
blur=X | f=blur:X
applies Gaussian blur
​Sharpen​
sharp=X | f=sharp:X
applies unsharp mask to sharpen the image
