If you generated the WebP images with a single extension (image.webp<\/code>) and want to use a plugin (like LiteSpeed Cache<\/a>) that requires WebP files with a double extension (image.jpg.webp<\/code>), you can either rename the WebP files manually or let ShortPixel handle the task.<\/p>\n\n\n\n

Manual renaming<\/h2>\n\n\n\n

To manually rename the files, you need access to a shell console with Bash<\/strong>. If you’re unsure, consult your hosting provider or a trusted developer.<\/p>\n\n\n\n

Simply run the following script to rename all images in a folder (provide the folder as a parameter):<\/p>\n\n\n\n

#!\/bin\/bash
cd $1
for file in *.webp
do
  if test -f \"${file%.webp}.jpg\"
  then
    echo \"${file%.webp}.jpg\" EXISTS. Moving \"$file\" to \"${file%.webp}.jpg.webp\"
    mv \"$file\" \"${file%.webp}.jpg.webp\"
  fi

  if test -f \"${file%.webp}.jpeg\"
  then
    echo \"${file%.webp}.jpeg\" EXISTS. Moving \"$file\" to \"${file%.webp}.jpeg.webp\"
    mv \"$file\" \"${file%.webp}.jpeg.webp\"
  fi

  if test -f \"${file%.webp}.png\"
  then
    echo \"${file%.webp}.png\" EXISTS. Moving \"$file\" to \"${file%.webp}.png.webp\"
    mv \"$file\" \"${file%.webp}.png.webp\"
  fi

  if test -f \"${file%.webp}.gif\"
  then
    echo \"${file%.webp}.gif\" EXISTS. Moving \"$file\" to \"${file%.webp}.gif.webp\"
    mv \"$file\" \"${file%.webp}.gif.webp\"
  fi
done<\/pre>\n\n\n\n
You will need to execute this in each folder or incorporate it into a shell script that traverses the directory structure. To achieve this, you can use a command like the following (assuming the script above is named replace-in-folder.sh<\/code>):<\/p>\n\n\n\n
find . -type d -exec .\/replace-in-folder.sh {} <\/pre>\n\n\n\n
Automatic renaming<\/h2>\n\n\n\n
Automatic renaming is only possible if you first restore all the images. Please note that unless you have an Unlimited plan<\/a>, this process will use additional credits. Follow these steps:<\/p>\n\n\n\n
    \n
  1. Restore your images.<\/a><\/li>\n\n\n\n
  2. Add the following constant to your wp-config.php file: define('SHORTPIXEL_USE_DOUBLE_WEBP_EXTENSION', true);<\/code><\/li>\n\n\n\n
  3. Optimize your images again while creating WebP files<\/a>.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
