Titanium Unlimited WebP Optimizer is a WordPress plugin that performs local image conversion to WebP format. It addresses the need for on-server image optimization without reliance on external services, uploads, API keys, credits, or usage limits.
The free version supports unlimited local conversion of JPG and PNG images from the Media Library. It creates WebP versions automatically for new uploads, runs bulk optimization through a background queue powered by WordPress cron that includes controls to pause, resume, stop, and monitor progress with elapsed time and live refresh. Users can perform one-click full optimization or use advanced manual tasks. It maintains a full image status database, checks for new uploads, offers missing-only conversion, full rebuilds, and retry for failed items. WebP files are generated for registered WordPress image sizes. The plugin also provides diagnostics for missing formats, missing WordPress sizes, metadata issues, and repairable source references along with Media Library WebP status tracking.
A Pro version adds AVIF support and additional site-wide image tools. The plugin is delivered as a standard WordPress plugin that runs entirely on the site owner's server.
