ImageMagick - 关于图片压缩，通过dk整理的一些可用指令 - window64

测试可以通过命令行批量处理指定类型图片，少量图片的话直接搜“图压”就行了，一般图片还是可以的

下载链接：https://imagemagick.org/script/download.php

window系统往下滑找到这个下载

 

指令：

进入对应文件夹下压缩所有jpg后缀的图片 （直接替换原文件）：

 magick mogrify -quality 85% *.jpg

 

压缩指定图片，后面名称跟前面一样的话为覆盖 ：

   magick 图片.jpg -quality 85% 图片2.jpg  

 

某些图片为扫描件，直接压缩没有效果     采用扫描噪点方式

magick 图片.png -colors 200 -define png:compression-level=9 图片2.png

------------------------------------------

后面的指令没试出啥效果，可能测试图片少了，可以自己试试

模糊降噪法： magick 图1.png -blur 0.05x0.05 -define png:compression-level=9 图2.png

尺寸欺诈术：magick 图1.png -resize 80% -define png:compression-level=9 图2.png

自适应调色板+选择性模糊  ： magick 图1.png -colors 128 -blur 0.03x0.03 -dither None -define png:compression-level=9 图2.png

需要其它指令直接根据需要问dk吧

补充一下可用脚本，新建bat文件代码复制进去，拖到对应文件夹下执行即可

pause
exit /b 1
