Images are core component of any site. Using them, we enhance content and make visitors more receptive to what we have to say. The downside of using many is that they tend to slow down a website. In this Optimole review, I will show how this image optimization plugin can help you.

It is crucial to optimize your images and increase page load time. This process decreases space your images take up and reduces your website loading times. In most cases, it will not noticeably impact the quality of pictures.

A large part of optimizing an image means compressing the file so that it takes up less space. Image optimization tools are designed to decrease the size of images as much as possible but still keep the image quality. Usually, there are three types of image compression.

Lossy compression (recommended) offers the best compression rate. This is the recommended option for most users, producing results that look the same as the original to the human eye.

Glossy compression creates images that are almost pixel-perfect identical to the originals. The best option for photographers and other professionals that use very high-quality images on their sites and want the best compression while keeping the quality untouched.

Lossless compression the resulting image is pixel-identical with the original image. Not a single pixel looks different in the optimized image compared with the original.

Image optimization also includes changing the dimensions of your images, changing the format, and server-side optimization so that images load faster.

If there’s something visitors to site don’t like, it’s a slow-loading site. Let’s be honest, we all leave the site if it takes too long to load. Page load times directly correlate with bounce rate and conversions, so you need to keep your site as fast as possible.

To avoid those negative outcomes, it’s important to optimize WordPress images. You can automate this process using WordPress plugins.


Optimole Review – Image Optimization Plugin

Optimole is an image optimization plugin from the folks at ThemeIsle. Two unique things about this plugin are that beyond the image compression and resizing; it also offers image acceleration through the plugin’s built-in CDN as well as built-in lazy loading.

I don’t know any image optimization plugin that offers CDN in price (ShortPixel also offers it). Both of these features are optional, so you can just use Optimole for compression.

Optimole plugin has a simple and modern interface with most of the tools running in the background without you knowing. It requires a quick account creation and API key insertion.

After that, you can view all optimized images in the dashboard and modify certain settings like image replacement, resizing of large images, compression quality, and lazy loading.

Optimole also has its own dashboard outside of WordPress. On your Optimole account, you can find more detailed information like the optimization sizes and monthly reports.

For image compression, Optimole lets you choose from three different levels of compression quality. Those are Low, Medium and High. I presume there are equivalents to lossless, glossy and lossy.

There is also an Auto option for compression, and you can have the plugin automatically resize images’ dimensions to a certain max height/width.

Optimole does all the compression on its servers, so it won’t slow down your site while compressing images. You can test Optimole and analyze to see how much you can save by entering your website URL on their site.


How Optimole Works?

Optimole comes in the free and paid plan. The number of images that you can optimize depends on your original image size and the number of optimizations you do for it.

Using the Free plan you can optimize up to 1 GB of images, which means around 2000 images at an average of 500Kb per image.

The free plan uses Optimole custom made CDN built with 7 locations around the globe. Paid plans have direct integration with Amazon CloudFront, with more than 130 locations around the globe.

Plugin connects via API to OptiMole image optimization service to send the images to its servers and crop, optimize and process them on-the-fly.

The EXIF data will be stripped, and it is not stored on servers. The plugin will rewrite your image URLs to replace them with Optimole URLs.

For integration with WordPress, you can download Optimole from WordPress repository. There is also an option to integrate using provided a script for HTML and custom integrations. After installing and activating Optimole plugin, you will be asked to enter an API key.

To receive API key, you will need to register for Optimole account which takes only a minute. When you register for an account, take your API key and enter it in required field on your website in Optimole plugin.

After that, you will have a new tab called Optimole under Media. Optimole consists of two tabs called Dashboard and Settings. From Dashboard section you can see all optimized images and by how much were they optimized.

Under the Settings tab, you will see that there is not much to do. Just a couple of features. Optimole is a very simple plugin for image optimization.

I would recommend it for beginners and people who don’t want to mess with many settings which offer most other image optimization plugins for WordPress.


optimole image optimization settings


Those settings include:

  • Enable image replacement – Replace all the image URLs from your website with the ones optimized by Optimole.
  • Admin bar status – Show in the WordPress admin bar the available quota from Optimole service.
  • Javascript replacement & Lazy load – Generate images size based on your visitor’s screen using javascript and render them without blocking the page execution via lazyload.
  • Resize large images – Resize all images with sizes greater than set values.
  • Compression level – A higher compression might result in a small loss of image quality. Select the most appropriate value for your images.

You might be asking what if the website already uses a lazy load like from WP Rocket (see WP Rocket vs Super Cache vs Total Cache) and the user also activates Optimole Javascript replacement & Lazy load? Will there be any conflicts?

I got response from Optimole developer that this depends which plugin registered first their routines for lazy load.  So it will load either the optimole script or the wp-rocket one.

I have tested this with WP Rocket lazy load installed and lazy load from Optimole enabled and there is no conflict. You can check image optimization stats, bandwidth, and traffic from your Optimole website account.


Optimole Pricing Plans

The Free plan allows for 1GB of images per month, a CDN, and 10GB of viewing bandwidth per month. The free plan uses custom-made CDN built with 7 locations around the globe.

Paid plans have direct integration with Amazon CloudFront, with more than 130 locations around the globe.

Be noted that there should not be any conflicts or issues if the website already uses some CDN like Cloudflare and no additional settings are required in that case.

Optimole Review Final Words

No matter how optimized your website is, images will always be one of the slowest-loading elements on the page. If you want to speed up WordPress website, you need to use a strategy that targets images specifically.

Optimole is a free image optimization plugin which can be downloaded from the WordPress.org repository. Optimole is a somewhat new addition to WordPress, but it is just as good if not better than most image optimization plugins.

Another significant advantage of using Optimole is the dynamic handling of images or videos which will resize and compress them instantly.

Using an API, this plugin rewrites your image URLs and replaces them with the resized and compressed ones from Optimole.

Optimole has options for auto, low, medium, and high compression depending on your needs. You can also choose to resize images above a certain size.

Optimole is intended for users who don’t want to spend much time on settings. Users who want a few simple steps and let the plugin do the work. And Optimole does its job very good.

They don’t delete the original images, so your original images are always secure. They serve the optimized images from their CDN (see best WordPress CDN) so there’s no need to back up your original images.

But some may want more features, and Optimole lack of them could be a no go. Turning on Lazy Load option will for maybe a sec replace images as you scroll with a blurred image.

This speeds up page load, but I don’t like that shadowy solution. I instead prefer that nothing is shown like WP Rocket has it managed.

Though plugin is simple without many settings, it would still be good that they have some documentation which is currently nowhere to be found.

To conclude, I would recommend Optimole as a great image optimization plugin for WordPress if you need a plugin which will do the job and you don’t need to play with settings. But if you need more from image optimization, then Optimole is not the choice for you.

And if you need to organize WordPress media files into folders, then be sure to check my FileBird review to see how it can be done for free.

  1. Thanks for a great article regarding the optimole plugin.
    Been using it for about 4 months now on our website and it seems to be serving its purpose fine in terms of functionality.
    Just wanted to find out why the test optimole link that was displayed further up in this article does not function and gives a page error.
    Keep up the great work

    1. Hi Mark,

      Thank you for sharing your feedback regarding Optimole and for letting me know about link which gives error. I have updated it.

  2. I tried optimole and didn’t work very well. Images disappeared or were sized incorrectly. I love some of the concepts but I won’t be using it unless it improves.

    1. Hi Christian,

      Thank you for sharing your experience in using Optimole. Have you tried contacting Optimole support regarding your issue?

  3. With them replacing my image urls with their own will this stop Google indexing images on my site? Will this mean I won’t appear for image searches on the site?

      1. I am using optimole since few months now, and its great! But recently created an image sitemap for better indexing results. I am not sure if I can include optimole image urls in my image site map. How to deal with this situation, as Google may not consider my images with canonical urls?

  4. This plug conflicts with google map service…. i am using directory theme from templatic,… perhaps optimole is doing its work even for images from google map service.? It would be great if we can exclude the processing of optimole by domain url,….. i only see option for exclusion by page, filename, and class name.

  5. This is complete and utter lies. I have just cancelled my subscription of optimole after having signed up to its service in April. According to google analytics, since installing it in April our website loading times have increasingly gone up month on month, whereas it had been decreasing month on month before using it. I’d love to hear a response on why this service did exactly the opposite of what its meant to do.

    1. Hi Jaytee,

      Sorry to hear you had such experience. Are you sure it it because of Optimole? Have you tried contacting their support regarding that?

    1. Yes, I can see. The main issue which Optimole should take care of is “Serve scaled images.”

      Are you using their CDN service for images and you are sure you setup everything correctly?

  6. “Through testing, I mostly didn’t like that there is no option to save and keep a backup of your original images.”

    We don’t delete the original images, so your original images are always secure. We serve the optimized images from our CDN so there’s no need to back up your original images. Hope you can update that in your review. 🙂

  7. When I replace my image to optimole plugin, my web site lost a lot of images. I would not recommend this plugin.

  8. I used Optimole and it really works well. I got 90 mobile performance grade , 92 performance desktop performance grade in google page speed. Optimole is really easy to set-up, in my opinion is better than resmush.it and wp smush.

  9. This is an awesome article! I usually skip through looking for the main points but I actually read every single word of this post haha. Website speed has been one of my biggest concerns. Namely pictures. As you can see on my website http://www.thepinkbrunette.com I have a ton of pictures. My fear of optimizing images was that I would lose the quality of my images. By the looks of it though, Optimole seems to negate that risk.

    With them replacing my URLs with their URLs, is there any risk of losing my content if I were to remove the plugin at any point?
