Description
OptiFlow WebP Media is a lightweight yet powerful WordPress plugin designed to optimize your website’s performance by automatically converting images to the modern WebP format. WebP images are significantly smaller than their JPG and PNG counterparts (often up to 30% smaller) without losing quality, helping your site load faster and improve SEO rankings.
Unlike other plugins that clutter your default uploads directory, OptiFlow WebP Media stores all converted files in a dedicated wp-content/webp-uploads folder, maintaining a clean and mirroring directory structure.
Features
- Automatic WebP Conversion: Automatically converts new JPG, JPEG, and PNG uploads to WebP.
- Bulk Conversion: Convert multiple existing images at once using the “Bulk Actions” menu in the Media Library.
- Full Library Support: Optimized all registered image sizes, including thumbnails, medium, large, and custom sizes.
- Dedicated Storage: Converted images are stored in
wp-content/webp-uploads/, keeping your standard uploads folder clean. - Dashboard Overview: A modern, high-quality settings dashboard to monitor your library’s optimization progress.
- Manual Conversion: Need to convert an old image? Use the “Convert” button directly in the Media Library list view.
- Intelligent Statistics: Correctly identifies native WebP uploads vs. converted images for accurate reporting.
- Custom Quality Control: Fine-tune your WebP quality (50-100) to find the perfect balance between file size and image clarity.
- Cleanup Tools: Option to automatically delete all generated WebP files if you decide to deactivate the plugin.

FAQ
-
Where are the converted images stored?
-
All converted images are stored in
wp-content/webp-uploads/. The plugin creates a folder structure that exactly mirrors your standardwp-content/uploads/directory for consistency and easy management. -
Does this delete my original JPG or PNG files?
-
By default, the plugin keeps your original images as a fallback. However, if you are strictly focused on saving disk space, you can enable the “Keep Original Images” setting to delete the originals after a successful conversion.
-
What happens if I upload an image that is already WebP?
-
The plugin intelligently detects native WebP uploads. It won’t attempt to re-convert them, and they will be marked as “Optimized” in your dashboard statistics.
-
How do I manually convert an old image?
-
Go to the Media Library (Media > Library). In the list view, you will see a “WebP” column. Click the “Convert” button next to any JPG or PNG image to generate its WebP version.
