How many images I can optimize with each plan?

The number of images that you can optimize or store is unlimited, we care only about the number of visits you have per month.

What happens if I exceed plan limits?

Once you exceed these, we will contact you and kindly ask to upgrade to the plan that fits you best.

What Content Delivery Network (CDN) do you use?

For both FREE and Paid plans we use AWS CloudFront CDN with more than 450 locations around the globe.

I’m already using a CDN, can I use that instead of yours ?

Short answer, YES. You will only need to whitelist the domain of your existing CDN for Optimole to pick images stored there.

I’m already using an image optimization plugin, why should I switch to Optimole?

You don’t need to change your existing optimization plugin, image optimization is just a small part of what we do, if you are happy with ShortPixel for e.g, feel free to continue to use it, Optimole would then take care only of serving your image at the RIGHT size, advanced cropping and smart lazy-loading.

Does Optimole handle images from Ajax content ?

Yes, we do. By default, Optimole handle images delivered from your ajax content from admin-ajax.php ( not logged in users ) as well as WordPress REST API routes.

Can I remove the blurry placeholder from the lazyload effect ?

Yes, you can. You only need to toggle this feature in the plugin as explained per this doc – https://docs.optimole.com/article/1020-can-i-remove-the-blurry-placeholder-from-the-lazyload-effct

Will the original images be deleted?

We use your original images as sources when deliver the optimized images. Unless you want to remove images from your server to save some space with Cloud Library by offloading images to the cloud as explained here – https://docs.optimole.com/article/1323-cloud-library-browsing

What is the difference between the Auto, High, Medium, Low compression levels?

A higher compression might result in a small loss of image quality. Selecting the auto level will let Optimole choose the minimum size with no loss in the quality of your picture.

I used Kraken, Shortpixel, Optimus, EWWW or WP Smush, Imagify will Optimole further optimize my images?

Yes, Optimole will also take care of serving your image at the RIGHT size for your visitors and optimize them to the best possible format for their browser.

Which formats can be optimized ?

For now we support jpg, png and svg format.

Does Optimole automatically serve WebP for Chrome users ?

Yes. We automatically detect user browser and serve WebP if is supported, otherwise we optimize the image in the original format.

Can I disable lazyload for PNG images ?

Yes. You need to add define("OPTML_DISABLE_PNG_LAZYLOAD",true); to your wp-config.php file.

You can also use plugin’s UI and exclude images by their type as explained here – https://docs.optimole.com/article/1191-exclude-from-optimizing-or-lazy-loading

Can I disable optimization for a certain image ?

Yes, you can exclude certain image by its name as explained here – https://docs.optimole.com/article/1191-exclude-from-optimizing-or-lazy-loading

In case you’re tech-savvy and want programatically exclude images by some conditions you can follow this code snippet and replace the sample image with the one you need or have other conditions:

add_filter('optml_dont_replace_url', function( $old, $url ) {
    if ( $url === 'https://example.com/wp-content/uploads/2018/09/1.jpg' ) {
        return true;
    return $old;

}, 10, 2);

Broke my site by updating image names & paths, when mesaly 1k limit exceeded, it broke my client’s site. They can’t revert back to my old paths to existing un Optimold optimized images. I had selected to leave images on my server & their cloud. Tried downloading image zip file but their new images weren’t included. Support said paying for their service wouldn’t fix. So now I’m fixing one by one manually, inexcusable.

Recently discovered (via a message in the Optimole Admin panel on our website) that there is a limit on the number of HOSTED images (50k on the starter package). Contacted Optimole who state in an email that there is a cap on the number of hosted images. Their own fair usage policy says that there is, quote: «no fixed limits on the number of images hosted», and the description on the official WordPress plugin site says in the FAQ section: «The number of images that you can optimize or store is unlimited, we care only about the number of visits you have per month». We reached to ask for a clear list of the number of images that can be hosted for each plan, but they don’t seem to want to tell us these numbers. If you are planning on hosting a lot of images. Becareful!

Optimole has been a game-changer for my website’s speed! Since installing the plugin, I’ve seen a noticeable improvement in page load times. The combination of lazy loading, CDN delivery, and automatic conversion to WebP and AVIF formats is fantastic. It’s clear they’ve put a lot of thought into offering a comprehensive solution. Plus, the setup was a breeze, and I haven’t had any conflicts with other plugins. Highly recommend!

A few years ago I switched from Smush to Optimole. One of the reasons was to have watermarking. A few months ago Optimole informed us that the limit of free images have been strongly limited and a paid subscription was required (or a commercial banner from Optimole on our site). As we are a small charity organisation helping street cats in the south of Spain,that totally depend on donations we cannot afford to pay a lot for software / plugins. I requested for a reasonable discount, but Optimole doesn’t want to do that. I have better experience with several other plugin providers. So we have been switching back to Smush.
