Q. How can I shrink jpg files?
A. Download Guetzli (for Windows) and ImageMagick (for Windows) and use like this:
convert myimage.jpg myimage.png
guetzli_windows_x86-64 myimage.png myimage_small.jpg
Guetzli only works on PNG files so you need to convert your JPEG to a PNG first.
When it runs, it takes minutes and uses lots of memory. But it usually can make your JPG 30% smaller (which is rather amazing)
