Hi I want to resize jpeg image that were uploaded as optimized, but because of a software error all recoded to 100% jpeg quality. (so we upload say 80% quality image and after upload it is 100% quality and the filesize is enormous!)
So how can I
- 1st find only jpeg images file that have a quality setting > 80
or better quality setting == 100
- and optimize these images only to a quality setting = 80
I appreciate your help
you can use jpegoptim for compress images using command
jpegoptim --all-progressive --strip-com --strip-exif --strip-iptc --strip-xmp -T1 -m80
