Good day. I need to optimize the images in the website, converting PNG/JPEG to webP format.
I tried several plugins like : Kraken, Shortpixel, Optimus, EWWW Optimizer, WP Smush, Imagify, WebP Express but none of this is available unless you pay for them. ( Exception for EWW Optimizer, webP express - free, but they require PHP 5.6 and upper, whereas the website is deployed in PHP 5.5 )
Is there any suggested plugin / solution ? I've also thinked of settings in side the .htaccess file and then serve the webP images, but the content writer will have to convert the images themselves ( so this is not optimal at all )
