From the developer
Qrzysio's own description of Force WebP, lightly tidied.
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
– thumbnails are written directly as WebP by WordPress itself – one lossy pass instead of two
– configurable WebP quality level
– optional maximum image width (original images are resized before thumbnails are generated)
– optional removal of the original JPG/PNG files to save disk space
– ICC colour profiles are preserved, so photos keep their colours
– self-healing metadata: broken thumbnail references are corrected automatically
– built-in repair tool for media libraries damaged by older versions
– 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.
Configuration
You can configure the plugin in Tools → Force WebP.
Available options:
– WebP quality (0-100): controls compression quality for newly uploaded images
– Max width (px, optional): limits the maximum width of original images before WordPress generates thumbnails (0 = disabled)
– Keep original JPG/PNG: keeps the source file after a successful conversion (off by default)
The same page offers a repair tool that fixes attachments whose thumbnails were broken by versions 1.2-1.5 (see FAQ).
All settings affect only images uploaded after saving the configuration.
