The tool utilizes PHP's built-in Imagick or GD library to handle image conversions. It processes images in batches of 20 to prevent server timeouts and can automatically resume if interrupted.

Codcy Image Optimizer includes a scanning function that reviews the entire WordPress media library, presenting users with a breakdown of image counts, file sizes, and format distributions prior to any changes. Users maintain control over the process, as no conversions occur until the start command is given. Upon completion, the plugin generates a detailed report summarizing the number of images converted, total space saved, average compression rate, and any errors encountered during processing. Installation is straightforward and does not require creating an account. 4 or higher. Its open source nature and lack of a subscription model make it accessible to site owners seeking a self-hosted image optimization solution.
