Description
ImageEngine Kube is enterprise-grade image optimization software that runs inside your infrastructure — not ours. You deploy it as a container in Kubernetes or Docker, point your existing CDN and image URLs to it, and get the same advanced optimization (device detection, auto-format conversion, smart compression) that powers 100,000+ domains — with none of the per-request billing.
Key Features of ImageEngine:
- Automatic Optimization: Effortlessly reduces image sizes by up to 80%, significantly speeding up page loading times on every device.
- Advanced Format Support: Automatically serves the best image format (WebP, JPEG XL, JPEG 2000, or AVIF) from a global CDN, ensuring optimal performance.
- Customizable Settings: Easily configure which WordPress directories to include, define excluded directories or extensions, and toggle HTTPS support.
- Seamless Integration: Works harmoniously with WordPress Cache Enabler, WooCommerce, Gutenberg, and major WordPress page builders like Elementor, Divi, and ThriveThemes.
- Enhanced Web Performance: Lower your website’s bounce rates and improve SEO by optimizing over 60% of your site’s content – its images.
- Supports ImageEngine Directives: Fine-tune image quality, format conversion, and resizing directly through ImageEngine’s directive settings.
- Third-Party CDN Support: Using an existing CDN? ImageEngine works seamlessly with top Content Delivery Networks (CDNs) for fast, worldwide image delivery.
