If the image itself is already very small, or the target size is set too small, it may not reach the target value.
We recommend increasing the target size appropriately, or check if the original image is already in a compressed format.
Yes, compression reduces image quality to reduce file size.
The closer the target size is to the original size, the less quality loss. We recommend setting a reasonable target size.
