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.

How to Speed Up Your WordPress Site

Learn how to speed up your WordPress site with ImageEngine.

How Should You Measure the Performance of a WordPress Image Optimizer?

  • Image Payload Reduction: Large images make up over 60% of an average website’s payload. Typically, ImageEngine can reduce image payload anywhere from 40% to 80%. An image payload analysis tool can quickly analyze one’s current website and provide an estimate of savings.
  • First Contentful Paint (FCP): Marks the time at which the first text or image is displayed.
  • Time to interactive: The amount of time it takes for the page to become fully interactive.

- Search Engine Optimization (SEO)/ Search Engine Results Pages (SERP): Image optimization has a significant impact on how search engine ranks a website. If a WordPress image optimizer succeeds in cutting seconds off the load time, then rankings should improve.

- Bounce Rate: The percentage of people who land on a website and do nothing on the page they entered.

- Conversion Rate: Every website measures a conversion differently. For example, some ecommerce sites measure the frequency of a user placing an item in a cart and purchasing. The superior user experience from ImageEngine in providing faster page loading drives improved conversion rates.

- Sales: Revenue is the most important indicator of success. Many ImageEngine users see an increase in revenue from both desktop and mobile user purchases. ImageEngine typically has a very strong Return on Investment (ROI) based on the revenue increase, simplified workflows, and overall CDN cost savings.

This 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.

  • Delivers optimized WebP, JPEG 2000, or AVIF images 30% faster than other CDNs or Digital Asset Management platforms.
