Output Quality q

Controls the output quality of lossy file formats (jpg, pjpg, webp, or jxr).

Valid values are in the range 0100 and the default is 75. Quality can often be set much lower than the default, especially when serving high-DPR images. See our srcset tutorial for more information.

When auto=compress is applied to an image, the default value becomes 45 unless overriden.

See the API specification for more information about this parameter's value ranges and format.
