Piio is the only technology that offers real high-DPR (device-pixel ratio) support. Our library understands the device and the DPR of that device, inherits the CSS options from your website and renders a pixel perfect image for that device in real time.
There's no need to update your code or change anything in your account to support new resolutions or new high-DPR devices.
What does Piio exactly do?
We multiply the container size of the image by the pixel ratio of the device, there are cell phones that have a DPR of 2.75.
