Technical details - A look at the inner workings

The WordPress plugin Webp Converter For Media is characterized by a well-thought-out technical architecture that enables efficient conversion of images to WebP and AVIF formats. At the file system level it uses custom PHP routines to dynamically switch the MIME type while keeping the image URL unchanged.

Developers can use an alternative loading path via PHP if the standard rewrite rules are blocked, which is controlled by specific .htaccess settings. It also supports image conversion from directories such as /plugins and /themes, which can be extended via hooks and filters. Integration of shortcodes and APIs gives developers additional freedom to create advanced implementations.

Criticism - potentials and problem areas of the plugin

Criticism of the Webp Converter For Media plugin covers several aspects that users have pointed out in their experiences. A frequently mentioned issue is the lack of communication and clarity from the developer regarding some plugin functions, particularly why conversion to the WebP format occasionally fails. Users also complain about the absence of warnings about the consequences of deactivating the plugin, which can lead to unexpected problems.

It is also reported that the plugin sometimes blocks the media library or increases the number of files, which can lead to unwanted effects on the website. These problems seem to occur especially with specific server configurations, such as blocked htaccess rewrites, which require technical support from the hosting provider. Another critical feedback concerns the removal function of already converted images upon uninstallation, which is perceived as inconvenient.
