Image Optimization

We have broken down this to 7 important components.

Responsive image resize

Result: Gumlet is better at resizing! πŸŽ‰

Both services have responsive resizes features. But Cloudimage's responsive resize rounds up the image size to nearest 100 multiple to save on image caching. Whereas Gumlet rounds up to nearest 10 multiple. This means that an image which takes up 355px on your screen would be served by Gumlet in 360px size whereas Cloudimage would serve it in 400px size. This way Gumlet would be able to provide more image optimization.

Image Compression

Result: A tie πŸ‘”

Both services use their own AI powered, perceptually lossless compression algorithms. Running a complete benchmark would be too much work and out of the scope of this comparison. However, Gumlet compresses SVG format images which is not supported by Cloudimage yet.

Auto WebP

Result: A tie πŸ‘”

Both services convert images to WebP whenever supported by browser.

Lazy Load

Result: A tie πŸ‘”

Both services offer lazy loading and progressive loading for a faster viewing experience.


Result: A tie πŸ‘” (?)

This is may be one of the 2 controversial topics of comparison in this entire blog.

Gumlet ensures that your image SEO remains intact by sending "canonical link" header to the search engines. This is done automatically for all users without any config required. Cloudimage does not do this.

This functionality is well supported by Google (Read more) and popular in the SEO landscape (Read more). It is also supported by lots of other WP plugins like ShortPixel.

On the other hand Cloudimage provides custom CNAME support with their deal and their basic plans. Setting your own custom CNAME would eliminate the requirement for "canonical link" header, but one has to contact their support team and do additional settings to get those features. If you don't do those additional settings, you would lose your image SEO.

Gumlet also provide custom CNAME support, but at an additional price. Please check pricing section for more details. At the end we leave the verdict on this one to users based on what is important for them. Β 

Image Caching

Result: Gumlet offers unlimited caching! πŸŽ‰

Both services cache the optimized version of your images. But Gumlet provides an unlimited free caching! Whereas Cloudimage has limits on how much image cache they would provide.

Content Delivery Network (CDN)

Result: A tie πŸ‘”

This could easily be the most controversial part of this comparison. Cloudimage marketing emphasis a lot on premium CDN providers to guarantee best performance world wide. However, there are no public benchmark available for the CDN they use. Gumlet uses AWS CloudFront for which there are a ton of publicly available benchmarks. According to this one has a CloudFront latency of 35 ms while the fastest CDN out there has a latency of 33 ms. Based on this we believe there can not be any "significant" difference in CDN provided by either services.

Service Parameters

After comparing the core image optimization functionality, let's see how both services compare in user experience related aspects.


Result: Gumlet wins! πŸŽ‰

Images are a very crucial part of your website's UX and hence reliability is Β a very important aspect.

Gumlet offers 99.9% uptime SLA vs Cloudimage's 99.5% uptime SLA.

More importantly, Gumlet has 3 image processing centers in Singapore, Frankfurt and San Francisco. Not only this allows us to process your images from the nearest center, it also makes our service fault tolerant. In an unlikely event of one region failing, our other region can automatically take up the load temporarily. We also have auto scaling mechanisms in place.

Compared to this Cloudimage has only 1 image processing center in Europe. As per our internal testing all the images are sent to Europe for processing.

Gumlet's service status is trackable on our status page, it is public and transparent. We could not find Cloudimage's status page.

Ease of Use

WordPress plugin result: A tie πŸ‘”

WordPress plugins for both service are super easy to integrate. Gumlet does have some advanced settings like ability to exclude images from optimization, but we will call it a tie here.

JS plugin result: Gumlet is easier to use! πŸŽ‰

We found that our JS plugin is much easier to integrate. While Cloudimage's documentation looks similar, but it requires a lot more work to extract the same image optimization performance.

For e.g. they require you to manually add aspect ratio for image image manually. Gumlet takes care of this automatically with Aspect Ratio Resize.

Also with Gumlet you can optimize image coming from multiple sources like Wasabi and DigitalOcean Storage which are not supported by Cloudimage yet.


Result: Gumlet is much more affordable and scale friendly! πŸŽ‰

Gumlet (pricing) is clearly the more affordable of the two services. For a website with about 50k monthly visitors and 200 GB image CDN usage. Gumlet would cost $20/month, while Cloudimage would cost Β about $115/month.

If you pay Gumlet $25/month, you would get custom CNAME support as well. (Please note that, this is not a total $45 / month for Gumlet as the CNAME support also comes with 250 GB/month of CDN usage)


Result: A tie πŸ‘”

Both services provide chat and email support.


Result: A tie πŸ‘”

Both services have in-depth analytics dashboards.

Advance features

These are the features that not every users require. We have just list them out without much explanation. Please reachout to us over support chat for more details on any of them.


To be honest both Gumlet and Cloudimage are great services for image optimization. Either service is better then most of the other solutions in the market. It's a win-win for the customers that both services are running a $49 lifetime deal on Appsumo.

We have tried our best present a fair and honest comparison which would help users decide in the easiest possible way.
