The "Freemium" Trap of Image Plugins
If you search for "optimize images WordPress," you will find dozens of plugins with millions of installs. They all promise to speed up your site, but they all share the same frustrating business model:
The Hook: "Optimize your images for free!"
The Limit: "...up to 50 images per month" or "max 5MB file size."
The Upsell: "Want to convert to WebP? Upgrade to Pro for $10/month."
Worse, these plugins often work by running heavy compression scripts on your server. This spikes your CPU usage, slows down your dashboard, and fills your hosting storage with backup copies of every single image.
It is 2025. You shouldn't be paying to resize JPEGs.
The Modern Way: On-the-Fly Optimization
The big tech companies (Facebook, Netflix, Amazon) don't compress images on their web servers. They use an Image CDN.
Instead of storing 10 different versions of photo.jpg (small, medium, large, webp, avif), they store one high-quality original. When a user visits the site, the CDN instantly creates the perfect version for that user's device.
Visiting from an iPhone? Serve a high-res WebP.
Visiting from Chrome on a 4K monitor? Serve an AVIF.
Visiting from a 10-year-old laptop? Serve a standard JPEG.
This happens in milliseconds, at the "edge" of the network, without your server doing any work.

Why AVIF Matters in 2025
You have heard of WebP, but AVIF is the new king of compression. It offers:
Smaller Files: 20-30% smaller than WebP (and 50% smaller than JPEG).
Better Quality: No "blocky" artifacts even at high compression.
HDR Support: Better colors and contrast.
Most WordPress plugins charge extra for AVIF support because it is computationally expensive to generate. StaticDelivr does it automatically on our powerful edge servers, ensuring your site is future-proof.
