The add-on automatically creates WebP versions of images in CS-Cart when files are uploaded and also provides a separate tool for bulk conversion of images that are already stored in the shop. If a WebP copy exists and the browser accepts WebP, the add-on substitutes that version in image and thumbnail paths.
Key features
- Automatic conversion to WebP on image upload.
- Selectable WebP quality from 10 to 100.
- Manual bulk conversion through a dedicated admin tool.
- Generation of WebP copies for source images and thumbnails.
- Path substitution to
.webp when the file already exists and the browser supports WebP.
- Exclusion of logos from bulk conversion.
How it works
- After an image pair is saved, the add-on can automatically create a WebP copy next to the original file if the related setting is enabled.
- After thumbnails are generated, the add-on additionally creates WebP versions of those thumbnail files.
- In manual mode, the ms_webp.convert tool iterates through linked shop images and converts them to WebP in bulk.
- When image pairs are loaded, the add-on checks for an existing WebP file and returns paths to
.webp when the browser accepts that format.
Where to find it in the admin panel: Modules -> Manage modules -> Automatic image conversion to WebP -> Settings, and also Administration -> WebP Conversion (dispatch=ms_webp.convert).
Important: The images/ directory must be writable. Before bulk conversion, it is recommended to create a backup of files and the database. Logos are skipped during batch processing.
