THE PROBLEM
Images are the biggest performance bottleneck on most WordPress sites
Images often make up most of a page’s weight. When they are not optimized, they slow down loading, affect user experience, and hold back overall performance.
Lower search visibility
Slow-loading pages can impact how search engines evaluate your site.
First impressions
Large images can delay page load and create friction before visitors start reading.
Delayed decisions
When pages feel slow, visitors are less likely to move forward or take action.
HOW IT WORKS
Intelligent image optimization that works
Robin automatically analyzes each image and applies the right level of optimization. It reduces file size while keeping visual quality intact, so your images stay sharp without manual effort.
Automatic optimization
Images are optimized as soon as they’re uploaded. Robin works quietly in the background, so you don’t need to manage images.
Flexible compression control
Robin supports lossless, lossy, PageSpeed-focused, and custom compression modes, giving you control over quality & performance.
Modern image formats
When supported, images are served in modern formats like WebP. AVIF is available in Pro, with safe fallbacks for browsers.
FORMAT COMPARISON
Serve the best image format, automatically
Robin automatically serves modern image formats when supported, with safe fallbacks when they are not. This reduces file size without changing how your site works.
JPEG & PNG
Legacy formats
Less efficient by today’s standards
Reliable and widely supported formats, but they typically produce larger image files than newer alternatives. This increases page weight on image-heavy pages.
WebP
FREE

Yes. The Agency plan is designed for client work and allows you to use Robin on client websites within your licensed site limit. You can manage and optimize images across all client sites from a single license.
Why do I have to pay for the plugin every year?
Your license helps us continuously improve Robin with new features, performance updates, security fixes, and compatibility with the latest WordPress versions, plus ongoing support when you need it.
How does Robin optimize images without losing quality?
