You can convert one image or a selection, and you can work through every image that is still waiting. Conversion runs on your server with WordPress’s image editor (Imagick or GD). Files are not uploaded to FlipWebP or any other service. An image is replaced only when the WebP version is meaningfully smaller. Animated GIF and animated WebP files are left unchanged. SVG files are never converted. After a successful conversion, FlipWebP updates the attachment and rewrites stored addresses in posts, comments, and settings so existing content keeps pointing at the image. Addresses inside serialized objects are left unchanged rather than risk corrupting them. #### What you can do * Convert the selected images on the FlipWebP screen. * Convert every waiting image, one request at a time, and stop after the current image. * Convert from the Media Library bulk action, a row action, or the attachment details panel. * Choose quality from 40 to 100 and an optional maximum dimension. * Delete the original only after a smaller WebP file is saved, or keep it. * Store a restorable backup in a protected folder under uploads. * Optionally convert new JPEG, PNG, and GIF uploads. This is off until you enable it. ## Installation 1. Upload the `flipwebp` folder to `/wp-content/plugins/`, or install the zip from Plugins Add New. 2. Activate FlipWebP through the Plugins screen. 3. Open Media FlipWebP. 4. Save the quality and backup settings, then convert a single image before running a large batch. The server needs Imagick or GD with WebP support. The FlipWebP screen shows whether that support is available. ## FAQ ### Does FlipWebP send my images anywhere? No. Images are read and written on the server that runs your site. The plugin does not phone home, and it does not load scripts or styles from another domain. ### Will existing posts keep showing the image? FlipWebP updates the attachment, then replaces the old uploads path in posts, comments, meta, and options. Clear any page cache or CDN cache afterward. Very large serialized values, and serialized values that contain objects, are skipped so they are not corrupted. If a reference cannot be updated, the original file is kept. ### What happens when WebP is not smaller? The original file is restored and the image is marked as unchanged. Convert all skips those images. You can select one later and try again after changing the quality. ### Are animated images converted? Animated GIF and animated WebP files are skipped so the animation is preserved. A static GIF can be converted. ### Can I get the original file back? Yes, when “Keep restorable backups” was enabled for that conversion. Use Restore on that row. Backups live in `wp-content/uploads/flipwebp-backups` and are blocked on Apache and IIS. On nginx, deny access to `wp-content/uploads/flipwebp-backups` and `wp-content/uploads/flipwebp-tmp`. ### Does this change the front of the site? No styles or scripts are added to public pages. The plugin loads its interface only in wp-admin. ## Reviews There are no reviews for this plugin. ## Contributors & Developers “FlipWebP” is open source software.
