SEO WebP Image Optimizer for Magento 2 User Guide

For a shopper-friendly overview of features and setup, see the Magento 2 SEO WebP Image Optimizer User Guide on the storefront. This wiki page remains the full technical documentation.

This is a Toweringmedia Magento 2 extension guide for the current admin extension catalog.

• SEO WebP Image Optimizer for Magento 2 (SKU tm-seo-images-webp)

This extension serves WebP versions of Magento catalog cache images on the storefront to reduce page weight and improve Core Web Vitals, and provides an admin bulk conversion tool for CMS and media library assets that sit outside the catalog image cache.

• WebP delivery for Magento catalog cache images on the storefront.
• Admin bulk conversion for CMS and media library assets.

• Magento 2.4.x (Open Source or Adobe Commerce).
• PHP: ~8.1.0||~8.2.0||~8.3.0 (as declared by the published package).
• A current Toweringmedia license and Composer credentials for https://composer.toweringmedia.com/.
• No other Toweringmedia packages are required.
• The server's PHP GD or Imagick build must support WebP. If it does not, conversion will fail regardless of configuration.

Install and validate in a staging environment before production rollout.

cd /path/to/magento
composer require toweringmedia/module-seo-images-webp
 
bin/magento module:enable Toweringmedia_SeoImagesWebp
bin/magento setup:upgrade
bin/magento setup:di:compile
bin/magento setup:static-content:deploy -f
bin/magento cache:flush

Currently published versions at the time of writing:

• toweringmedia/module-seo-images-webp — 1.0.6

Toweringmedia packages are served from the licensed Composer repository https://composer.toweringmedia.com/. If Composer reports that the package could not be found, your credentials are missing or the license does not cover this package yet. Retrieve your keys from My Account on toweringmedia.com, or contact support@toweringmedia.com.

General installation notes that apply to every Toweringmedia extension are in the installation guide.

The storefront product is named SEO WebP Image Optimizer, but the Composer package is toweringmedia/module-seo-images-webp and the Magento module is Toweringmedia_SeoImagesWebp. The install command above uses the real package name.

• Stores > Configuration > Towering Media > SEO Images WebP (config section seo_images_webp), group general.
• Admin screens: Intelligence SEO Suite > Images WebP (configuration shortcut) and WebP Optimizer (bulk conversion tool).

1. Confirm WebP support exists in your PHP image library before enabling.
2. Enable storefront delivery, flush cache, then load a category page and check in browser dev tools that catalog images are served as WebP.
3. Run the WebP Optimizer for CMS and media library assets separately — those are not part of the catalog image cache.

• Storefront catalog delivery and admin bulk conversion are two separate mechanisms. Enabling one does not do the work of the other.

• bin/magento module:status shows the module(s) as enabled.
• Extension configuration saves without errors in Admin.
• The admin screens listed above are reachable and load without error.
• Expected storefront/admin behavior is present after a cache flush.
• No critical PHP/JS errors appear in var/log/ during the primary test flow.

• Composer cannot find the package: confirm the https://composer.toweringmedia.com/ repository and your credentials are present in auth.json, and that your license covers this package.
• Feature not visible: verify module status, flush cache, and redeploy static content.
• Admin setting not applying: clear cache and confirm the config scope (default / website / store view).
• Unexpected behavior: retest with only the required related modules enabled.
