Using WebP Format to Optimize Image Performance in Drupal

Staff Reporter

Juan Delgado Salmerón's blog post on Drupal Sapiens outlines how using WebP format can significantly enhance image handling and site speed in Drupal. WebP, developed by Google, offers superior compression and supports modern features like transparency and animation, making it a smart choice over JPEG or PNG for most Drupal sites.

The post focuses on Drupal 10, where native WebP support is built into core. Delgado provides a step-by-step walkthrough to enable WebP via the image styles UI, specifically using the “Convert” effect. This eliminates the need for additional modules or custom code for sites running version 9.2 or later.

While the performance benefits—up to 50% smaller images—are substantial, the post notes WebP may be unnecessary for sites with few images. The article is technically accurate but could offer more detail on compatibility fallbacks or edge cases. Overall, it’s a useful primer for site builders optimizing front-end delivery.
