What is Optimus?

Editorial review

Optimus is a WordPress plugin designed to optimize images by significantly reducing their file size without compromising visual quality. It achieves this through lossless compression for PNG images and slightly lossy compression for JPEG images. Unlike many other tools, Optimus not only compresses original images but also all generated preview images (thumbnails) within WordPress. The plugin further enhances optimization by removing unnecessary metadata like EXIF and IPTC data from JPEG and PNG files, which can lead to file size reductions of up to 70%. It also generates progressive JPEGs and converts images to WebP format. The compression process occurs discreetly in the background on Optimus servers, ensuring user privacy. This tool is ideal for WordPress users, website owners, and developers looking to improve website loading times, SEO rankings, and overall user experience by serving optimized images. Key benefits include faster website performance, improved PageSpeed scores, reduced traffic thanks to smaller images, and compatibility with WordPress Multisite and WooCommerce. The software is developed in Switzerland and hosted in Germany, emphasizing data privacy and continued development.
