[英]Resize jpeg images only where the quality >80 using either mozjpeg/jpegtran/jpegoptim
问题描述
Hi I want to resize jpeg image that were uploaded as optimized, but because of a software error all recoded to 100% jpeg quality. 
嗨，我想调整上传为优化图像的jpeg图像的大小，但是由于软件错误，所有图像均重新编码为100％jpeg质量。 (so we upload say 80% quality image and after upload it is 100% quality and the filesize is enormous!) （因此，我们上传的图片质量为80％，上传后的图片质量为100％，文件大小非常大！）
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 因此，我如何-1st 仅找到quality setting > 80或更高quality setting == 100 jpeg图像文件，并且仅将这些图像优化为quality setting = 80

您可以使用命令“ jpegoptim --all-progressive --strip-com --strip-exif --strip-iptc --strip-xmp -T1 -m80”使用jpegoptim压缩图像
