HK Media Optimizer

HK Media Optimizer is a WordPress plugin designed to identify and remove unused media files from the WordPress Media Library, helping site owners reclaim disk space. It addresses the challenge of accumulated, unreferenced media files by scanning the library and pinpointing which files are no longer used anywhere on the site. This process enables users to safely delete unnecessary files without risking the loss of content that is still in use.

The plugin distinguishes itself by running scans in small, configurable batches via AJAX, ensuring that it does not overload the server, even on modest shared hosting environments. Unlike more resource-intensive media-cleaning tools, HK Media Optimizer is built to minimize the workload of each request, making it suitable for a wide range of hosting setups. Users have control over the scanning process, with the ability to enable or disable specific scan sources and protect recently uploaded files from deletion.

HK Media Optimizer checks for media usage across several areas of a WordPress site, including post and page content, featured images, direct attachment relationships (such as files uploaded into a post), custom fields and post meta, and values stored by the Advanced Custom Fields (ACF) plugin if it is active. Additionally, it scans widgets—including block-based widgets—Theme Customizer settings like logo, background, and header image, as well as the site icon. This comprehensive approach helps ensure that only genuinely unused files are flagged for removal.

The plugin is delivered as a downloadable extension from the WordPress Plugin Directory. Its focus on lightweight operation and configurable controls makes it suitable for WordPress users seeking an efficient way to manage media storage without risking server performance or accidental data loss.
