If you need to update Magento 2 WebP Images Extension by Magefan, please follow the steps below.

Note: the updating instructions depend on the method the WebP images extension was installed with.

Update using composer

composer remove magefan/module-NAME
composer require magefan/module-NAME ^x.x.x
# replace NAME with:
# webp - for Basic plan
# webp-plus - for Plus plan

# replace x.x.x with the version you want to use
php bin/magento setup:upgrade
php bin/magento setup:di:compile
php bin/magento setup:static-content:deploy

Update using archive and FTP

1. Download the latest version of the WebP images extension archive from magefan.com.

2. Extract archive.

3. Make the backup copy of the app/code/Magefan/WebP,  app/code/Magefan/WebPPlus and app/code/Magefan/WebPExtra folders on your server and then remove them.
