ImageRecycle just updated their PHP script for image and PDF compression. It’s fully optimized to work with Magento 2, Drupal, OpenCart, and TYPO3. They’ve also improved the script admin UX. Note that the PHP script can work with any CMS/system on the market!
Currently, they are working on improving the WordPress multisite image compression and bringing a new design to the WordPress and Joomla extension. Image resizing will be added as option into the CMS script.
The PHP script is now fully optimized to work with PrestaShop and Craft CMS too.
