Image Format Converter allows administrators to convert images in the WordPress Media Library between JPG/JPEG, PNG, WebP, and AVIF formats. Using server-side PHP libraries (GD or Imagick), it ensures high-quality conversions with minimal file size. Converted images are saved to the uploads folder and optionally added to the Media Library.
Features: 
– Select images via the WordPress media uploader. 
– Choose target format (JPG, PNG, WebP, AVIF). 
– Configure quality/compression and Media Library integration via a “Conversion Settings” button (admin-only). 
– View server library status (GD/Imagick/WebP/AVIF) with a “How to Enable GD and Imagick” button for setup instructions. 
– Modern, clean interface inspired by professional design standards (e.g., TinyJPG-like cards and buttons). 
– Secure, efficient, and admin-only (no frontend features).
Access all features on Media > Image Converter, with collapsible settings and instructions.
