Standard Web WP Image Optimizer

Standard Web WP Image Optimizer is a lightweight and performance-focused WordPress plugin designed to generate and serve optimized WebP versions of JPG and PNG images.

Unlike many image optimization plugins that rely on aggressive rewrite rules, output buffering, or frontend JavaScript, this plugin uses safe WordPress-native filters to deliver generated WebP images with minimal overhead and high compatibility.

The plugin is designed for real-world shared hosting environments, including cPanel hosting, while still scaling efficiently on VPS and dedicated servers.

Compatibility Notes

• The plugin does not require .htaccess rewrite rules.
• The plugin does not require frontend JavaScript.
• Original JPG and PNG files are always preserved.
• The plugin automatically disables processing features if the server is incompatible with WebP generation.
• Shared hosting environments are supported if WebP support is available in the server image libraries.

Key features include:

• Automatic WebP conversion for newly uploaded images
• Bulk optimization for existing Media Library images
• Queue-based processing system to avoid timeouts

The plugin avoids unnecessary frontend overhead by:

This makes it suitable for performance-focused WordPress websites that need predictable behavior and low server impact.
