Plus WebP or AVIF

It is very useful to replace the URLs of images of existing content as well.

Easy and very useful


I really like this plugin and it's very good in other aspects. However, on both of my websites, when converting in bulk, I was unable to continue the conversion for a certain period of time, indicating an Ajax 500 error. What is the reason?


500 error


This is great plugin to save my server space!



Dear developer, I prefer to donate by paypal, usdt or stripe instead of inputting my credit card elsewhere.


Great plugin

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.
Explore <a href="https://meowapps.com/wp-retina-2x" rel="nofollow ugc">our official site</a> and check out <a href="https://meowapps.com/wp-retina-2x/tutorial/" rel="nofollow ugc">the tutorial</a> to get started.
<h3>Core Features</h3>
⚙️ Image Size Management 
The foundation of everything. View all registered image sizes (WordPress defaults, theme sizes, plugin sizes), disable the ones you don’t need, and add custom sizes. Finally, control over those pesky WordPress-generated sizes like <code>medium_large</code>, <code>1536x1536</code>, and <code>2048x2048</code>.
🔄 Regenerate Thumbnails 
Bulk regenerate thumbnails after changing sizes or switching themes. Progress tracking, smart processing, and automatic cleanup of old unused sizes.
🖼️ Retina Images (Module) 
Optional module for high-DPI displays. Automatically generate and serve crisp @2x versions of your thumbnails. Works seamlessly with WordPress responsive images.
🎨 Modern Formats (Module) 
Optional WebP/AVIF conversion. Convert images to modern formats for smaller file sizes and faster loading—without replacing your originals.
🚀 Easy IO (Module) 
Optional CDN-based image optimization via EWWW. Automatically converts and delivers your images in WebP/AVIF, resizes on the fly, and serves them from a global CDN—zero server configuration required.
🤖 AI Features (Module) 
Optional AI-powered tools. Upscale images via Claid.ai when your source is too small, or use the AI Assistant to analyze your sizes and recommend which to enable or disable based on your theme’s srcset needs.
