Frequently Asked Questions

Common questions about ShortPixel Adaptive Images - WebP, AVIF, CDN, Image Optimization

In your WP dashboard you will be warned when your quota is about to be exhausted and also when it has been exceeded. When the quota is exhausted, the plugin will simply serve the original images from your server, without compression or resizing, until the quota resets.
ShortPixel Adaptive Images uses bunny.net to offload the images - a global CDN with over 90 edge locations around the world. Both the free and paid plans use the same CDN with the same number of locations. You can check for yourself how the bunny.net CDN compares to other CDN providers - here (worldwide) and here (North America).
Sure. Here is how to configure it with Cloudflare and here’ is how to configure it with STACKPATH. Please note that if you use another CDN instead of CDN traffic, image credits will be consumed. If you need further help, please contact us.
