What It Does

Make your website faster by reducing the weight of images. Our WordPress image optimizer plugin can cease image weights on 80% without any loss of quality.

Robin image optimizer is a smart and advanced image optimizer that really stands out among other WordPress plugins. It is a free image optimizer plugin with zero limitations in terms of number of images and optimization quality. The only thing that you may stumble across is the image weight, which shouldn’t exceed 5 MB.

The lighter the weight of the image – the faster your page loads. With the constant growth of mobile users, the necessity for mobile website optimization increases. If you don’t want to get many rejections and lose money due to poor ad performances, we’d recommend you to start with image optimization.

This plugin is absolutely free and has the same features as paid products. It offers automatic optimization using Cron, meaning you don’t need to wait until optimization is completed; the plugin will optimize several images every few minutes in the background. You can also perform manual mass-optimization with just a button press.

Before optimization starts, all images are stored in original quality, allowing you to restore lost images or re-optimize them later. You can choose from different compression modes, affecting image weight and quality. The plugin also provides detailed statistics on optimized images.
