The WebP extension creates
.webp versions of already uploaded images and displays them, if the requesting browser supports WebP images.
This extension requires
libwebp to be installed on the server.
Thumbnails can both be generated on parse or through thumb.php, they require that the source file is converted to webp.
This can be done by running
php extensions/WebP/maintenance/ConvertImages.php --no-thumbs.
thumb.php links don't contain the
.webp extension, the returned thumbnail will be a webp file.
More information can be found in the Readme.

A maintenance script exists to convert already uploaded images:
php extensions/WebP/maintenance/ConvertImages.php # To only convert non-thumbnails run php extensions/WebP/maintenance/ConvertImages.php --no-thumbs # To create thumbnails of custom sizes run # This will create two thumbnails with size 1000px and 1250px php extensions/WebP/maintenance/ConvertImages.php --thumb-sizes=1000,1250 # To only work on some images run php extensions/WebP/maintenance/ConvertImages.php --titles=ImageA.jpg,ImageB.png # To force the creation of already existing images run php extensions/WebP/maintenance/ConvertImages.php --overwrite # Only work on page titles matching a prefix # Every page starting with prefix 'Example' will be selected php extensions/WebP/maintenance/ConvertImages.php --title-prefix=Example # Only work on page titles matching a file-type # Every page starting with file-type 'png' will be selected # Can be combined with 'title-prefix' php extensions/WebP/maintenance/ConvertImages.php --file-type=png
