Image Blur is a WordPress plugin that simplifies the process of creating blurred placeholders for images. This tool is particularly beneficial for developers seeking to maintain an attractive site design while images load. Upon activation, it generates base64 encoded, downscaled, and blurred versions of images from the media library, ensuring users have a seamless experience during loading times. The blurred images can be easily accessed and utilized within the media library, making it a practical solution for enhancing site aesthetics.

Customization options are a key feature of Image Blur, as it allows developers to modify the width and strength of the Gaussian blur effect. By default, the plugin generates images that are 8 pixels wide, but this can be adjusted using specific hooks to suit individual requirements. This flexibility positions Image Blur as a valuable tool for WordPress developers, providing an efficient way to implement image placeholders tailored to their unique needs.
