I used all the free CDN quota with your CDN service, what happens next?
Once all the free image optimization credits are used for a website, whether you are using Autoptimize or ShortPixel Adaptive Images, the system will return to the original images. This means that your website, instead of displaying the optimized images from our CDN, it will display your original images.
In terms of speed, this means that your site will load slower, as it did before starting to use ShortPixel.
