SiteByter Image Optimizer is a WordPress plugin designed to compress JPG and PNG images within a site's media library. It utilizes the image editor built into WordPress, specifically GD or Imagick, to perform the optimization process directly on the local server. This approach ensures that no images are transferred off the server, and there is no need for API keys, accounts, per-image charges, or monthly quotas.
Key features include lossy compression for JPG and PNG files with adjustable quality settings ranging from 1 to 100. The plugin can automatically downsize oversized uploads to user-defined maximum dimensions, helping to control file sizes and maintain consistent image quality across the website. Bulk optimization is supported, allowing users to process their entire media library at once, with a real-time progress bar to track the operation. Additionally, SiteByter Image Optimizer can automatically compress images as they are uploaded to WordPress, streamlining the workflow for site administrators and content creators.
A full backup system is included, preserving original images before any compression or resizing is performed. This ensures that users can restore their original files if needed. The plugin is available for free for local server use, offering unlimited image optimization without external dependencies. For those seeking to compress images stored on cloud storage, a Pro version extends this capability, although details about the Pro features are only briefly mentioned.
SiteByter Image Optimizer is aimed at WordPress site owners and administrators who want to improve page load times and manage image assets efficiently without relying on third-party services.
