I'm trying to minimize some JS code, with a smaller size. I tried all free-tools, and it minified 20% more or less from original size. The problem, is that GTMetrix says me I can do it until 60% with most of them. Anyway, I didn't found a minimizer with that potential.
Do someone knows about a paid-or-free tool that can follow GTMetrix directrices to make JS as small as it says I can do it? Thanks
Anyway, my website is on Magento 1.9.x and it got his own automatic function to minimize JS activated. But is so bad optimized to do it.
