PNG图片批量压缩exe工具+功能纯净+不改变原始尺寸
小编最近有一篇png图片要批量压缩,大小都在5MB之上,在网上找了半天要么就是有广告,要么就是有毒,要么就是功能复杂,整的我心烦意乱。
于是我自己用python写了一个纯净工具,只能压缩png图片,没任何广告。在windwos平台上使用。
指定的压缩质量:40
压缩前图片大小
压缩后图片大小
可以看到图片从5MB压缩到了 500KB。指定的质量还是降低,压缩尺寸效果还可以更大。
压缩前和压缩后图片对比
压缩前,大小5.7MB:
压缩后,大小861KB:
使用视频教程
png压缩
代码采用python编写,打包成了exe, 文件目录:
直接运行这个 "批量压缩png图片.exe" 即可。
