Our verdict on Optimus
Optimus is a WordPress image-compression plugin for bloggers, photographers, editorial teams, and website owners. It automatically optimizes uploaded originals and generated thumbnails, making it suited to sites that need straightforward image processing inside WordPress. JPEG and PNG files are supported, with lossless PNG compression and slightly lossy JPEG compression. Bulk optimization covers existing images, while optional metadata preservation gives administrators control over EXIF and IPTC data.
The plan structure is based on fixed-term, one-time purchases rather than monthly subscriptions. The free Optimus plan supports JPEG and PNG files, unlimited images, and progressive JPEGs, with a 100 KB file limit. Optimus HQ costs $39 for 1 year or $89 for 3 years and adds WebP conversion, HTTPS connections, and the same unlimited image processing. Optimus HQ PRO costs $169 for 1 year or $389 for 3 years, adding permission to use the product in customer projects. Paid plans list a 10 MB maximum file size.
Optimus fits a WordPress-centered workflow particularly well because it supports WordPress Multisite and WooCommerce alongside standard WordPress installations. Its strongest use case is simple bulk optimization for a site owner or content team that wants automatic handling of originals and thumbnails without a broad image-processing platform. Buyers who need WebP output must choose a paid plan, and the free tier's 100 KB limit narrows its usefulness for larger uploads. Agencies and developers working on customer projects should consider the HQ PRO licenses, while users seeking optimization beyond the WordPress ecosystem may prefer a more platform-agnostic tool.
