quality

Type: String
Default: undefined

Instructs pngquant to use the least amount of colors required to meet or exceed the max quality. If conversion results in quality below the min quality the image won't be saved.

Min and max are numbers in range 0 (worst) to 100 (perfect), similar to JPEG.

speed

Type: Number
Default: 3

Speed/quality trade-off from 1 (brute-force) to 10 (fastest). Speed 10 has 5% lower quality, but is 8 times faster than the default.
