The correct optimized format is then chosen automatically based on the visitor’s browser, making your images fully compatible with new and old browsers. ### **✅ Automatic unlimited features the moment you activate** * AVIF-first optimization: Convert to AVIF and compress images for browsers that support the AVIF format * WebP fallback: Convert to WebP and compress images for browsers that support WebP but do not support AVIF yet * MozJPEG fallback: Use the 100% compatible MozJPEG format to optimize images automatically for older browsers without AVIF and WebP support * Smart format negotiation selects the best format automatically, eliminating browser compatibility issues * Pixy Speed Mode makes all optimizations in real time, so you can have a faster website instantly * Works with every web server (Apache, LiteSpeed, Nginx) without manual configuration * Lightweight – works on every web hosting plan, VPS and dedicated server * Works with page caching plugins and Cloudflare out of the box * Bulk optimize images and your entire library to WebP, AVIF or WebP+AVIF ### **🪄 Convert AVIF** Enjoy the unparalleled speed of the new AVIF format, completely free with Pixy, even if your hosting does not support convert to AVIF.

Pixy caters to visitors with older browsers too, by serving the WebP and even original images on the oldest browsers automatically. ### **🚀 Speed Mode** Pixy Speed Mode allows your website to start serving AVIF and WebP images instantly, without waiting for bulk optimization of your media library.

For more advanced ways to check which format is being used for an image, please refer to our documentation. ### Does it work on local WordPress installations? No. Your website needs to be reachable over it’s IP address or Pixy will fail to activate. ### What happens if I delete the plugin?

Pixy works on Nginx web server out of the box when Speed Mode is enabled. ### Which directories can I optimize? With Speed Mode enabled, Pixy optimizes any file on your website in real time.

Its lightweight and works out of the box. Speed Mode is very nice. Bulk optimization is slow because their is only the free plan available at the moment. Cant wait for the Pro options. But even the free version is incredible powerful.
