What is a Retina image and how to check Optimole is serving the Retina images?

A  Retina image is an image created specifically to look sharp on a Retina display. Retina screens, also known as HiDPI screens, feature a significantly higher pixel density compared to standard screens. Consequently, images must be twice their original size to ensure that everything appears crisp and well-defined on these high-resolution displays.

If you're using a Retina display and you observe that the images appear slightly  blurry after optimization, it's advisable to activate this option. By enabling the "Retina images" feature, the images will be fine-tuned to display correctly on Retina screens.

Enable the Option

To serve the Retina image, enable the Retina images option in Optimole settings ( Advanced > Resize ).

📝 Note: You need to have our lazyload enabled for images to be optimized for retina displays.
