Device Detection

Device detection is an image CDN’s first and most critical step. It detects the requesting device model and all capabilities that impact image size and quality. This includes operating system version, screen pixel density, screen resolution, and support for next-generation image and video file formats.

Image Optimization

An image CDN will leverage the device detection parameters to automatically resize, compress and convert large original images into optimized images with next-generation file formats. These optimized images are tailored specifically to a requesting device. Frequently, an image CDN will reduce the image payload by up to 80%.

Global Content Delivery Network (CDN)

An image CDN has edge servers strategically positioned around the globe. These edge servers detect devices and cache optimized images. When a similar device requests an image again, the image CDN responds immediately with the already-cached optimized image. By pushing optimized images closer to requesting customers with logic to deliver immediately from cache, an image CDN can often provide a 50% faster web page download time.

Our WordPress plugin rewrites your image URLs to include the ImageEngine Delivery Address you recieve when you sign up for an ImageEngine account. This rewrite will allow ImageEngine to access your original images, instantly optimize and convert them, and deliver via the ImageEngine CDN. After configuring and enabling the plug in, optimized image files are delivered this way:

  • When a visitor requests an image, ImageEngine CDN servers use client hints or device detection to identify the requesting devices and browser characteristics.
  • Based on the browser characteristics, ImageEngine will resize, compress and convert image files to JPEG 2000, AVIF, or WebP formats.
  • The optimized image file is delivered from the nearest ImageEngine CDN region. Subsequent requests are served instantly with WebP, JPEG 2000, or AVIF images and stored on ImageEngine’s global CDN.

Other static content like fonts, CSS and JavaScript are also optimized by applying Brotli or gzip compression which dramatically reduces that size of heavy WordPress themes.
