Perfect Images handles the basics of WordPress image management that should have been built-in from the start. Manage image sizes, disable the ones you don’t need, add custom sizes, and regenerate thumbnails in bulk. It’s the essential foundation every WordPress install needs for clean, efficient image handling. Think of it as your image management base layer. WordPress creates too many sizes? Disable them. Need a custom thumbnail size? Add it. Want retina support or modern formats like WebP/AVIF? Enable those modules. Perfect Images gives you complete control without bloat.
