PNG optimization however will run through both `optipng` & `pngquant` (if installed) as this can result in better optimization. It is highly recommended to install the necessary optimization tools, however they are not required to run goptimize. -Goptimize will remove all exif data from JPEG files, auto-rotating those that relied on it. +Goptimize will remove all exif data from JPEG files, auto-rotating those that depend on it for orientation.
