Cloudflare Image Resizing – Optimize & Accelerate Your Images

描述

Elevate your site’s performance with this plugin that dynamically optimizes and resizes images using the Cloudflare Image Resizing service.

Experience a significant speed boost by delivering AVIF/WEBP images from Cloudflare’s global locations directly to your users’ browsers.

The plugin utilizes the fastest available PHP functions, without any database calls, ensuring minimum overhead in performance. Your website’s speed will not be compromised, but it will noticeably improve.

Benefits

  • Refines your images, delivering higher clarity and enhanced quality, as opposed to standard WordPress cropping which often reduces image quality.
  • Supercharges your website speed, offering users an improved, faster experience by loading images from Cloudflare CDN, far quicker than traditional servers.
  • Boosts your SEO significantly due to superior website performance and speed.
  • Relieves your web hosting of heavy load, as asset loading is a prominent issue for servers, particularly Apache.
  • Conserves substantial bandwidth on your web hosting, an especially noticeable benefit for websites featuring numerous images/photos.

How does this work?

The Cloudflare Image Resizing plugin for WordPress enhances your site’s speed and performance by automating image resizing using Cloudflare’s advanced technology. But how exactly does this work? Let’s simplify it.

Usually, when you upload an image to your WordPress site, it creates multiple sizes of the image to fit different screen sizes, which can slow down your site. This plugin eliminates that issue.

The plugin taps into WordPress’s image management functions and changes the final URLs of the images in your site’s HTML code. Instead of pointing to the images on your server, these URLs now point to Cloudflare’s Image Resizing service.

When users visit your site, they aren’t just served images. Cloudflare resizes and optimizes these images on-the-fly, ensuring they’re perfectly sized for their device, enhancing load times and user experience. All this happens behind the scenes, making your website faster without any extra effort from you!

Current features

  • Substitutes all attachment/single image source URLs.
  • Replaces all multiple image source set URLs.
  • Revises all other image source URLs found within the content.
  • Provides the original image to Cloudflare Image Resizing service for efficient cropping.
  • Supplements missing image default sizes (width/height), enhancing Google Page Insights scores.

Compatibility

  • Latest WordPress and PHP 7+
  • All general themes
  • MAI Themes and Genesis Framework
  • DIVI Themes
  • Content Areas (formerly Template Parts)
  • Editor plugins like Visual Composer
  • Optimization plugins like WP Rocket

Notes

  • Before using this plugin please ensure you have turned ON the Cloudflare Image Resizing feature for your domain.
  • If your WordPress resides in a sub-folder, adjust the plugin settings by specifying the folder name.
  • You have the option to tweak quality settings, though it’s generally best to stick with the default configuration.
  • If images aren’t being re-written as expected, consider enabling more “hooks”. If the issue persists, feel free to open a support ticket.
  • The plugin allows for whitelisting of images sourced from platforms like Facebook, Twitter, Instagram, PayPal, etc.

Quick Guide and Tips

Checking if Cloudflare Image Resizing is Working

Once you’ve activated the Cloudflare Image Resizing plugin, you might be wondering how to check if it’s doing its job. Here’s a quick way to verify:

  1. With your site open, activate the developer console in your browser. This is typically done by right-clicking on your webpage and selecting “Inspect” or “Inspect Element”.
  2. In the console, navigate to the “Network” tab.
  3. Reload your webpage. You should now see a list of items that are being loaded on your page. You’re interested in the images.
  4. Look for any image files in this list (they’ll typically end in .jpg, .png, etc.). Click on an image to view more details.
  5. Look at the URL or the response headers for that image. If you see reference to the Cloudflare Image Resizing format, it means your plugin is working correctly and your images are being optimized.

Addressing Filename Issues

The Cloudflare Image Resizing plugin works by identifying the images on your site and applying optimizations. However, it can get confused if the filenames of your images are too complex or contain multiple dimensions.

For example, an image file named “image-100×200-100×300.jpg” might not be processed correctly. If you find that some images aren’t being resized, consider renaming these files and re-uploading them to your site. Simpler names, like “image1.jpg” or “product-shot.jpg”, are usually best.

Remember, the goal of image resizing is to deliver the most optimal version of an image for every user. So, it’s always a good idea to test this functionality on different devices and browsers to ensure all your users are getting the best experience possible.

At first I wondered why Cloudflare Image Resizing never seemed to work. Turns out, it is NOT automatic. This plugin immediately started working and thanks to CF resizing I’m saving a huge amount of bandwidth from these resizes (my other CDN claims to do resizing, but apparently not well). Very simple to set up and immediately starts working once it is, all you really need to make your site faster if you upload very large source images.

I just wanted to write this review to thank the developer. Using Cloudflare workers requires lots of code understanding. Thank you for developing a simple plugin that just integrates into cloudflare and does this automatically for us. Much much appreciated

Excellent work, easy to configure and exactly what Cloudflare image resizing is missing. Without having to manually change anything on your site, works pretty much out of the box and delivers a superior user experience for visitors.
