Image Quality Control | Still BE

Our WordPress plugin offers precise control over image compression in your media library. You can optimize the compression quality for each resized image, striking the perfect balance between visual appeal and fast page loading. A real-time preview feature lets you instantly see the results of different compression levels.

Security is enhanced through an EXIF data removal function, which strips sensitive information like GPS coordinates from your uploaded images.

For advanced performance, the plugin utilizes WebP technology on compatible servers. It automatically generates and serves WebP versions of your images to supporting browsers, replacing JPEG or PNG formats without manual URL adjustments. This seamless optimization significantly improves Core Web Vitals (CWV), enhancing your site’s overall performance and search engine ranking.

• Set the quality level in the image type (JPEG / PNG / WebP) and size name table.
• Set the default quality level if not set.
• Set the quality level for WebP compression of the original image.

Automatic optimization (version 2.0+) Version 2.0 adds SSIM-based automatic compression optimization. It runs in the background via WP-Cron, searches for the lowest quality level that still meets the target structural similarity for each image size (using the quality table as the ceiling), and records progress and total size reduction in attachment metadata. This feature is disabled by default (beta).

Stable release: The stable tag on the plugin directory is 1.7.4 — the last proven release before automatic optimization was introduced. Install version 2.0 or later when you want SSIM auto optimization.
