Appearance
Retina Quality
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. This feature is enabled by default with the "Quality Optimized" preset mode.
