When the image is requested, Optimole will apply the specific transformations required by the device and deliver it to your visitors. This means every image is perfectly sized for every device. The final result will be cached for a month to ensure ongoing fast delivery and more site speed.
**How many images can be optimized?**

Better yet. The free version is fully functional and includes all of the following great features:
**Format Based Optimization**
Our cloud-based transformation process means we can optimize images based on the format as well as serve images in next-gen formats. If your visitor is using a WebP capable browser, then Optimole will convert to WebP the image and send it to their device. AVIF support included.
**Cloud Library support**
Offload your website images directly to Optimole Cloud and save storage space on your server. Cross share images between your all your websites connected to Optimole.
**Image Optimization**
Our algorithms crunch the numbers to provide the best lossy or lossless optimization for the best-looking image at the smallest size using Machine Learning(ML) powered compression.
**Exact Used Size**
Optimole will use just one image and resize it delivering a responsive image to fit perfectly on your visitors' devices. No more awkward guesses at potential screen widths. Serve scaled images instantly.
**Retina Support**
Optimole can detect Retina screens and deliver an image with the perfect Digital Pixel Ratio (DPR).
**Smart Cropping**
If you'd like to keep the most interesting part of an image; then you can enable smart cropping to help keep the image well sized without losing focus.
**No Content Shifting**
The lazy load option defer offscreen images and is perfectly sized for the container to provide a seamless viewing experience without any content shifting.
**Watermarks**
Who has time for adding watermarks? Optimole will do the hard work for you. Just set it up and pick your preferred location and Optimole will add the watermark to all of your future images.
**Downgrade Quality For Slower Connections**
Optimole provides an option to downgrade the image quality when it detects a slower network. Efficiently encode images by making up to 40% smaller with this neat feature to help visitors in a bottleneck.
**Compatibility**
Optimole loves page builders and has unique tweaks to solve image replacements. It also has full compatibility with the new block editor since WordPress 5.0
**CDN**
Optimole provides free access to a AWS CloudFront CDN with edge locations in more than 200 cities around the globe.

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

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.
