Simple WP Retina


Seamlessly switches out images on Retina and other high pixel density screens with @2x versions.

The switch happens server side saving on HTTP requests.

No action is required on your part other than to activate it and to regenerate your thumbnails with the Regenerate Thumbnails plugin.

Plugin automatically:

  • Detects a HighDPI screen such as a Retina display
  • Detects all image sizes added using add_image_size() and adds @2x versions.
  • Replaces featured thumbnails and content images with the @2x versions for users with HighDPI screens.


Setup is easy.

  1. Upload plugin folder to the /wp-content/plugins/ directory
  2. Activate the plugin through the ‘Plugins’ menu in WordPress
  3. If you already have images on your site, running the Regenerate Thumbnails plugin will help by generating the new image sizes created by the plugin.


It does not work for me

Are you using any form of caching? Unfortunately the plugin currently does not play friendly with caching.

It works, but the images served on high pixel density screens are the full size images.

Running the Regenerate Thumbnails plugin will help by generating the new image sizes created by the plugin.

The images still look pixelated on high pixel density screens

The plugin can not scale up images. In order for this to work, the original images need to be at least double the dimensions of the desired image size.
