How does the plugin work?
When you upload an image (JPEG, PNG, or GIF), this plugin automatically converts it to WebP format, optionally strips metadata, optimizes for SEO, and supports lazy loading using WordPress hooks. You can also choose to delete the original image to save space.
What metadata gets removed?
The plugin can remove EXIF data, GPS coordinates, camera information, and other metadata that might be unnecessary for web display while maintaining image quality.
Can I control the quality of the WebP images?
Yes, you can set the quality level (between 0-100) or enable lossless compression for WebP images on the settings page.
Will this plugin replace the original images?
You have the option to either keep the original images or replace them with the optimized WebP versions.
Does the plugin support lazy loading?
Yes, it adds the loading="lazy" attribute to WebP images, improving page load times. This feature can be enabled or disabled in the settings.
Does the plugin optimize images for SEO?
Yes, it automatically sets alt and title tags for images based on the file name or post title, improving search engine visibility.
Does the plugin integrate with caching plugins?
Yes, it sets appropriate cache headers for WebP images to ensure compatibility with caching plugins like WP Rocket or W3 Total Cache.
What happens to temporary files?
Temporary WebP files are stored in a dedicated directory and automatically deleted after 24 hours using a scheduled cleanup process.
Does the plugin work with WooCommerce?
Yes, it works seamlessly with WooCommerce, converting and optimizing product images.
What if my server does not support WebP?
If your server does not support WebP conversion (e.g., if the imagewebp function is not available), the plugin will log an error, skip the conversion process, and store logs for recovery.
