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.

🔌 Enable the Feature

To enable this feature, navigate to WP  Dashboard > Optimole.


Open the Settings tab.


Expand the Advanced accordion and open the Resize panel.


Use the toggle to enable the Retina Quality feature.

📝  Note: Please remember to disable the "Limit image sizes" option if you plan to use the Retina option. Keeping this option enabled will disable the retina functionality as described in the feature - 🚀

🚀 User Site and Image Impact

Enabling Retina Quality means your website pictures will be incredibly sharp, especially on high-quality screens like those in iPhones and some laptops. Every small detail, like patterns and lines, will appear very clear and impressive. Despite these high-quality images, your website will still load quickly. This feature ensures your site looks professional on advanced screens without slowing down, providing visitors with a great experience.

To see if your images are displayed in high quality with the Retina Images feature, open the image URL and look for the dpr:2.0 parameter. If you find this, it means you're serving Retina Images through Optimole. 

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