💡 Why choose FastPixel Caching plugin?

  • Website Performance Boost: Just activate the plugin and within seconds the optimized webpages will start to be served.
  • Lower the CPU/RAM Impact: Using the plugin will reduce the impact on the resources used by your website. All the CPU intensive processing is done in the cloud and resulting pages will generally be served from a cached version and the optimized images from the CDN.
  • Automated Core Web Vitals Optimization: FastPixel takes care of all technical aspects automatically.
  • Smart Cache Warmup/Update: The cache warmup and update are taken care of automatically in a smart way. Pages are cached as they are visited and also updated if you update the content.
  • Critical CSS: CCSS is automatically generated for each page for lightning-fast page loads.
  • CSS/JS Processing: CSS/JS files are combined and also minified and compressed before they are served from our CDN.
  • HTML Optimization: A single, highly optimized HTML file is generated, adaptively serving the ideal webpage based on the visitor’s viewport or device (e.g., mobile, tablet, laptop).
  • DNS Preconnects: Accelerates resource fetching, reduces the access time to external resources.
  • Font Processing: All the techniques to accelerate the processing and delivery of fonts are employed, e.g. font subsetting, font loading control, font compression, font embedding (lower CLS result).
  • Image Resizing & Optimization: Images are automatically resized to fit their placeholders, optimized, and delivered through the ShortPixel CDN.
  • Automatic Next-Gen Images Delivery: Based on the visitor’s browser capabilities, original JPG, PNG, or GIF images are converted to and served as WebP or AVIF when supported. For browsers without support, the original format is provided.
