cwebp parameters #
Here are some commonly used parameters for cwebp:

-q, --quality: Set the quality factor for the output image. The value should be between 0 and 100, with 100 being the highest quality. For example, --quality=80.
--lossless: Encode the image without any loss. For images with fully transparent area, the invisible pixel values (R/G/B or Y/U/V) will be preserved only if the --exact option is used..
-m, --method: Set the compression method. The value can be 0 (fastest), 1 (default), 2 (slowest), or 3 (best quality). For example, --method=2.
-f, --filter: Set the filter strength. The value can be between 0 and 100, with 0 being no filtering and 100 being maximum filtering. For example, --filter=50.
-s, --size: Set the target size for the output image. The value should be in bytes. For example, --size=500000.
