    Hi Corn,

    What downsides are you referring to? If you’re asking if there’s any loss in quality, then no, there shouldn’t be any noticeable difference.

    When this option is enabled Smush will first check if there will be a difference in size when the image is converted to JPG, and if there’s no improvement then the image will stay intact, also, if the PNG image is transparent it will not be converted because JPG images don’t support transparent backgrounds.

    One thing to check when this option is enabled is if you have any PNG images hardcoded in your site, if you do those will need to be changed to JPG image links after the optimization is finished.

    Best regards,
