常见问题:
Which image types can this plugin convert?
The plugin supports JPEG, PNG, and GIF input formats, and converts them all to WebP. WordPress-generated thumbnail sizes are converted automatically alongside the original.
Does the plugin convert thumbnails too?
Yes. The plugin converts the main attachment file and all WordPress-generated image sizes when available.
Does this plugin send my images to an external service?
No. All conversion and bulk-processing code is first-party and runs entirely on your own server using GD or ImageMagick. No external services are contacted and no third-party libraries are bundled.
Can it convert images automatically on upload?
Yes. Automatic conversion can be enabled so every newly uploaded JPEG, PNG, or GIF is converted to WebP the moment it's added to your Media Library.
What happens during bulk conversion?
The plugin prepares the image list, processes images in batches, updates progress live in the admin UI, and records the results in the dashboard so you can track converted, pending, and failed images as it runs.
Can I restore the original images?
Yes. The plugin can remove the generated WebP files and switch delivery back to your original media files at any time — for a single image or in bulk.
Does it support both ImageMagick and GD?
Yes. The plugin supports both engines, with automatic detection depending on availability and your selected settings.
Is there a Pro version?
Yes. WebP Converter & Image Optimizer Pro is an optional add-on that runs alongside this free plugin and adds Conversion Quality control, an image-type filter, System Logs, Replace URLs in Post Content, Large Image Scaling, a filtered Images screen with per-image actions, before/after Image Comparison, Pause/Resume and Restore-All for bulk runs, media offload / CDN compatibility (Amazon S3, Cloudflare R2, DigitalOcean Spaces, Google Cloud Storage), and secure SVG uploads with sanitization. Details: https://apps.spinxdigital.com The free plugin remains fully functional without it — conversions are unlimited and nothing is time-limited or locked.
How do I get support?

更新日志:
- Improved: Media Library screens load much faster on sites that offload media to cloud storage (Amazon S3, Google Cloud Storage, and similar). The plugin no longer checks remote storage paths when looking for local WebP files, which previously added a network request for every image shown.
- Improved: WebP image dimensions are now read from the file header instead of loading the whole image into memory, lowering memory use when displaying WebP details.
- Tested with WordPress 7.1.
- New: optional server-level WebP delivery. Choose "Server rewrite (.htaccess)" in Settings to serve WebP files on the original image URL via rewrite rules in uploads/.htaccess (Apache/LiteSpeed), with automatic fallback to the original image for browsers without WebP support.
- The server rewrite mode covers images referenced anywhere — page builders, theme templates, CSS — and keeps serving WebP even while the plugin is deactivated. The rules are removed when the plugin is deleted or the delivery method is switched back.
- Restoring an image works exactly as before: the WebP file is deleted and the server automatically serves the original again. No content or database URLs are modified by this delivery mode.
- Default behavior is unchanged: the existing PHP filter delivery remains the default.
- Performance improvement change.
- Plugin URI updated to the official WordPress.org plugin page.
- Improved plugin architecture, portability, security, and performance.
