About this plugin
rMG – Image Optimizer improves image delivery by analyzing how images are actually displayed on your published WordPress pages.
Instead of only compressing uploads or relying on existing WordPress thumbnail sizes, rMG can inspect selected public pages at configured desktop, tablet, and mobile viewports. It measures displayed image dimensions and creates separate optimized variants for those placements.
Your original Media Library uploads remain unchanged.
Optimize the rendered page
rMG focuses on how images are used after the page layout has rendered. This helps reduce the delivery of images that are much larger than the space where they appear.
Key features include:
- Post-render analysis of selected published pages.
- Right-sized variants for desktop, tablet, and mobile viewports.
- WebP and AVIF output formats.
- Page-specific image optimization and reoptimization.
- Adjustable quality, sharpening, lazy loading, and fade-in controls.
- Page-level image savings and optimization status.
- Management and removal of generated variants.
- Original Media Library uploads remain untouched.
If an optimized variant is unavailable, the original image remains available as a fallback.
rMG is a free service provided by ProxSEO.
External Services
This plugin connects to the hosted ProxSEO rMG image optimization service when an administrator starts site optimization, requests optimization for a page, or runs queued background optimization.
The service analyzes selected published pages, measures displayed image dimensions, and returns analysis results to the WordPress site. The plugin creates optimized image variants locally on the WordPress server.
The service may receive:
- The site URL and site name.
- The installed plugin version.
- The installed WordPress version.
- Selected published page URLs or page IDs.
- Configured viewport names.
- Image and page metadata required for optimization.
The service may request selected publicly accessible pages to analyze how their images are displayed to visitors.
