Snake Image Optimizer
Snake Image Optimizer is designed for site owners who want a straightforward, local-first workflow for image optimization. Instead of depending on an external optimization API, the plugin works with local server capabilities to generate WebP and AVIF files for uploads and WordPress-generated image sizes. Original files remain available as a safe fallback. This version is intentionally focused on a small, practical workflow: Local WebP/AVIF conversion for uploaded JPG and PNG images. Safe fallback behavior that keeps the original files available. Automatic AVIF/WebP delivery through WordPress image handling. Lazy Load controls with a built-in page test tool. Diagnostics to help confirm local WebP/AVIF support. Activity logs for troubleshooting conversions and plugin actions. Bulk processing for eligible existing Media Library images. This plugin is best suited for users who want: a local-first approach; no dependency on a remote compression service; visibility into what the plugin is doing through logs and diagnostics; and a safer workflow that keeps originals available.
