🧞‍♀️ How Pixy Works

As soon as Pixy is active, it makes optimized copies of your original images in real time. It compresses them and converts them to WebP and AVIF formats. 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 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. AVIF is the successor to WebP, making images up to 50% lighter than WebP without quality loss. AVIF is now supported by all major browsers including Chrome, Firefox, Edge, Opera and Safari, with 94% of visitors globally using a browser that supports the new format. Pixy caters to visitors with older browsers too, by serving the WebP and even original images on the oldest browsers automatically.

🚀 Speed Mode

It uses smart real-time compression settings to make your images as fast as possible while preserving quality. When speed mode is used, optimized versions of your images don’t take any space in your media library.

External services

Pixy Image Optimizer connects to the Pixy API to activate the plugin for a website and to refresh the PageSpeed score shown in the plugin dashboard.

When you activate the plugin, it sends your website domain or site URL, your website’s public IP address, and a temporary verification challenge to the Pixy API. This is required to register the website and complete the initial connection between your WordPress site and Pixy.

When the plugin refreshes the PageSpeed score shown in the dashboard, it sends the registered website identifier and the homepage URL to the Pixy API. This is required to request and display the latest PageSpeed measurement for the connected website.

When you deactivate the plugin, it sends the registered website identifier to the Pixy API so the website can be disconnected cleanly.

When Speed Mode is enabled, image requests are served through Pixy’s image optimization and delivery infrastructure so images can be converted to AVIF or WebP, optimized, and delivered in the appropriate format for the visitor’s browser.
