How to Manage Your WordPress Images on the Cloud for Better Performance

Images are the most important form of content whether you’re running a company site, an ecommerce site or even your own personal blog. According to a study, articles with images get 94% more total views than articles without images.

While images are important, it’s often the main cause for slow loading websites. Optimizing images aren’t an easy feat.

Sure you could install a plugin to optimize your WordPress images. Yes, you could upgrade your server for more bandwidth and faster performance. But what if you could manage your images on the cloud for even better performance?

What’s Image CDN?

Image CDN is a cloud-based service that provides end-to-end image management and delivery. It’s smart enough to know the best version of an image and serve that automatically. Think of it as CDN built specifically for images. Hence, the name — Image CDN.

Before we dive deeper into image CDN, you need to know why your most important assets could bring the biggest performance drawbacks. It eventually hurts your SEO.

There are few reasons images are slowing down your website:

  • Incorrect image size and format.
  • Too many HTTP requests.
  • Lack of server bandwidth.
  • Lack of server storage.

While some of the issues above are related to the image file directly, others might be caused by cheap and slow shared hosting providers.

With image CDN, you’re not only leveraging on the CDN’s distribution networks for faster and more efficient images delivery. But also their technology to optimize image quality, file size and most importantly image format for your audience.

In this post, I’m going to show you how to manage your WordPress images with Cloudinary.

Why Cloudinary?

It’s the only image CDN that provides a free plan and you could grow your usage when you shared it on social media.

With the free plan, you’re entitled to 25 monthly credits.

1 credit allows 1,000 image transformation or 1GB managed storage space or 1GB bandwidth. Plenty to get you started.

What’re Cloudinary’s Key Features?

URL based image transformation: Like other image CDNs, Cloudinary supports URL based. To see it in action, we’re going to the demo image from Cloudinary.

Transform image URL: https://res.cloudinary.com/idemo/image/upload/c_fill,e_sharpen:200,g_faces,h_247,w_355/sofa_cat.jpg

You get a smaller image with sharpen effect.

You’ll get a smaller image with sharpening effect.:

Take note on the added parameters on the URL “c_fill,e_sharpen:200,g_faces,h_247,w_355”, this basically inform Cloudinary to do the following tasks:

  • c_fill: Crop the image
  • w_355 and h_247: Resize it to 355px * 247px
  • g_faces: Focus on the detected face (don’t ask me how but Cloudinary is smart enough to detect faces
  • e_sharpen:200: Sharpen the image by 200

Automatically adjust compression quality: Compressing images quality and encoding settings could reduce file size significantly without causing degradation in quality. Cloudinary takes care of that for you. Its algorithm would find the optimal balance and produce the best image while minimizing the file size. You could enable this by adding “q_auto” on the image URL.

Automatically select the best format: Google introduces Webp — a modern image format that provides superior compression resulting in smaller file size. Unfortunately, it’s only supported by Chrome. Simply append “f_auto” on the image URL and let Cloudinary do the hard work. Cloudinary will detect user browsers and deliver the most efficient image format for each image automatically.

As you see, the image is manipulated and delivered on-the-fly.
