Stories Image Optimizer automatically converts your uploaded images to next-generation WebP or AVIF format, providing better compression while maintaining quality.

Features:

  • Automatic conversion on upload to Media Library
  • Support for WebP and AVIF formats
  • Configurable quality settings for each format
  • Automatic image resizing based on max dimensions
  • EXIF/metadata stripping for smaller file sizes
  • Bulk optimization for existing images
  • Fallback from Imagick to GD Library
  • Keeps original files as backup (optional)

Why use WebP/AVIF?

  • WebP – 25-35% smaller than JPEG with similar quality. Supported by all modern browsers.
  • AVIF – 50% smaller than JPEG with better quality. Supported by Chrome, Firefox, and Edge.

How It Works:

  1. Upload an image to WordPress Media Library
  2. The plugin automatically converts it to your chosen format (WebP or AVIF)
  3. All generated thumbnails are also converted
  4. The converted file replaces the original in your content

System Requirements:

  • PHP 7.4 or higher
  • WordPress 6.0 or higher
  • GD Library with WebP support, OR
  • Imagick extension (recommended for best performance)
