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:
<ul>
<li>Local WebP/AVIF conversion for uploaded JPG and PNG images.</li>
<li>Safe fallback behavior that keeps the original files available.</li>
<li>Automatic AVIF/WebP delivery through WordPress image handling.</li>
<li>Lazy Load controls with a built-in page test tool.</li>
<li>Diagnostics to help confirm local WebP/AVIF support.</li>
<li>Activity logs for troubleshooting conversions and plugin actions.</li>
<li>Bulk processing for eligible existing Media Library images.</li>
</ul>
This plugin is best suited for users who want:
<ul>
<li>a local-first approach;</li>
<li>no dependency on a remote compression service;</li>
<li>visibility into what the plugin is doing through logs and diagnostics; and</li>
<li>a safer workflow that keeps originals available.</li>
</ul>
