Description
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 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 conversion for uploaded JPG and PNG images.
- Safe fallback behavior that keeps the original files available.
- Automatic WebP delivery through WordPress image handling.
- Lazy Load controls with a built-in page test tool.
- Diagnostics to help confirm local WebP 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.
