详情介绍:

This plugin converts every uploaded JPG or PNG image into modern WebP format to improve performance and reduce file size. Key features:

automatic conversion of JPG and PNG images to WebP on upload
correct generation of all WordPress image thumbnails
configurable WebP quality level
optional maximum image width (original images are resized before thumbnails are generated)
automatic removal of original JPG/PNG files to save disk space
full compatibility with WordPress “big image scaling”
automatic alt text generation based on the filename
filename sanitization and collision-safe renaming All settings apply only to newly uploaded images. Existing media files are not modified.

安装:

Download the plugin or install it from the WordPress Plugin Directory.
Activate it via the Plugins menu in WordPress.
From now on, any JPG or PNG file uploaded to the Media Library will:
be converted to WebP
have the original file removed
receive an alt text based on the filename
be renamed to avoid overwriting if duplicates exist

升级注意事项:

1.2 Major internal improvements. Correct thumbnail generation, optional maximum image width support, and better compatibility with WordPress image scaling.

常见问题:

Does the plugin support GIFs?

No. Only JPG/JPEG and PNG are supported. Other formats remain unchanged.

What happens if the server does not have Imagick with WebP support?

The plugin deactivates itself and shows an admin notice. Please enable Imagick with WebP support on your server.

How can I change the compression quality?

The default is 90%. You can change it in Tools → Force WebP. The new quality will be applied to all images uploaded after you update the setting.

Does the plugin generate WordPress thumbnails correctly?

Yes. Images are converted to WebP only after WordPress finishes generating all intermediate image sizes, so thumbnails work exactly as expected.

What happens to very large images?

If a maximum width is configured, large images are automatically resized before thumbnails are generated. WordPress backup originals are removed to avoid duplicate files.
