Did you know ?
Faster images increase conversion and thus revenue.

Cloudimage resizes, optimises, compresses and distributes your images lightning fast over CDN on any device around the world.
Apply image filters, custom transformations and watermarks to get the most out of your images and convert more users thanks to beautiful and fast images.
Embeds lazyloading and progressive loading effect for best user experience.

The Cloudimage WordPress plugin leverages the Cloudimage v7 API and offers 2 options for making images responsive on your theme:

  1. Using standard HTML5 srcscet tags.
    Your WordPress theme must natively support the HTML5 tags for responsive images above.
    By using this method, images in the WordPress media gallery will also be delivered over Cloudimage.

  2. Using the powerful Cloudimage Responsive JS Plugin.
    The plugin smartly identifies the image container width and delivers the optimal image size.
    No need for your Theme to support responsive images.
    It also adds lazyloading and progressive loading effect to your images for best user experience.
    This option makes the lightest possible output code and does not modify images in the WordPress media gallery.

No development needed, it’s plug-and-play!

Simply register for a free Cloudimage account and enjoy fast and responsive images.

To start boosting your images, create a free account at Cloudimage to obtain a Cloudimage token.
You get 25GB of CDN traffic and image cache for free every month. If you exceed this limit, we will contact you to set up a paid plan.
But do not worry, 25 GB should be enough for any small to medium-sized WordPress site.

More information on our paid plans here.

How does it work
The Cloudimage plugin will rewrite the WordPress image URLs and replace them with Cloudimage URLs.
Your origin images will be downloaded from your storage (WordPress media gallery, S3 bucket, …), resized by Cloudimage and distributed over CDN.
No development needed.

Question 1: How does Cloudimage resize and optimise my WordPress images?

Upon first load of your WordPress site after activating the Cloudimage plugin, the origin images will be downloaded by the Cloudimage image management infrastructure, resized, optimised and delivered over CDN to your end users.

Cloudimage adds an additional layer of image cache (shield) on top of the CDN to make every further request from the CDN to an origin image fast.
Cloudimage does not store your WordPress images permanently, you should always keep your images in your WordPress gallery.

Question 2: Why are my images not going through Cloudimage?

Check if you have a Cache service like W3 Total Cache / WP Super Cache / …
In this case, you need to reload the cache to enable the transformation of your URL.

If the problem persist please contact us.

Question 3: How much does Cloudimage cost?

Cloudimage is a SaaS with a free tier subscription for 25GB CDN traffic and 25GB image cache per month.
We offer paid plans with higher CDN traffic and image cache allowances, pricing here.

Question 4: Will my origin images be affected?

Cloudimage donwloads your images on-the-fly and does not modify your origin images.

Question 5: What happen if I deactivate Cloudimage WP plugin?

Your WordPress site will be back as it was before the activation of the Cloudimage Plugin. We do not apply permanent changes to your WordPress site and/or origin images.

Despite having tried many different solutions for increasing loading speed of images on website, this by far is my favorite tool. Everything works quite well, the customer service are supporting as well.

Would recommend for my friends! I noticed a quicker page load time right away, and installation was simple and straightforward. Support Department responds swiftly and is also quite educational.

Had some issues with loading images. Had a call in minutes, they found the problem. updated to the latest version. Everything is working now! Fast and furious! It is not about the problem, but about solving the problem (and how friendly you are-:) That is where the differnce is made! The key for succes in (online) businesses

Was searching for an image CDN. Tried but realized they are destroying SVG images in a weird way and most of the time images are not loading at all. After contacting support and trying to fix they told me it got fixed (how would they know) - but still no images and broken SVGs. Lets see, may try in future - at the momement i cannot recommend to anyone.
