Parameter | Description |
ObjectKey | Object name, such as folder/sample.jpg . |
/quality/<Quality> | Absolute quality of the image. Value range: 0−100. Default value: quality of the input image. The smaller value between the input image quality and the specified quality is used.

/rquality/<quality> | Relative quality of the image, relative to that of the input image. Value range: 0−100. For example, if the input image quality is 80 and rquality is set to 80 , the quality of the output image is 64 (that is, 80 x 80%). |
/lquality/<quality> | The lowest quality of the output image. Value range: 0−100. If the input image quality is 85 and lquality is set to 80 , the quality of the output image is 85.If the input image quality is 60 and lquality is set to 80 , the quality of the output image will be improved to 80. |
