Repository metrics are context, not quality scores. Active installations measure adoption and can strongly reflect a plugin’s age and historical popularity. Ratings, recent updates and “Tested up to” metadata also do not guarantee modern code, error-free operation, security, feature completeness or suitability for a particular site.

WP PlugIndex currently records Imagi Boost version 1.1.1 as active, updated 1mo ago and tested up to WordPress 7.1.
Overview
About this plugin
Image Boost is a free, powerful image optimization plugin that works 100% locally on your server. Unlike other optimization plugins, Image Boost requires no API keys, makes no external requests, and has no usage limits. Your images never leave your server.
It uses your server’s built-in Imagick or GD library to intelligently compress JPEG, PNG, GIF, and WebP images — reducing file sizes by up to 60% without visible quality loss.
🚀 Why Image Boost?
100% Local Processing — No API keys, no cloud uploads, no privacy concerns
Zero Usage Limits — Optimize unlimited images, forever
Smart Compression — Imperceptible quality loss with significant file size reduction
WebP Delivery — Automatic <picture> tag output for modern browser support
One-Click Bulk Optimize — Process your entire media library in minutes
Full Backup System — Every original is safely backed up and can be restored instantly
WooCommerce Ready — Works with product images, galleries, and all custom post types
⚡ How It Works
Upload an image normally to your Media Library.
Image Boost automatically compresses it in the background (if auto-optimize is enabled).
A WebP version is generated and served to supported browsers via smart <picture> tags.
View savings per image directly in the Media Library, or check the beautiful Dashboard for overall stats.
