CheetahO also allow users to resize images during image optimization process. Update “Resize my full size images” parameters to desired image size in pixels and try to optimize images.

Do not forget to update CloudFlare credentials if you are using CloudFlare. CheetahO will update CloudFlare cache when image will be optimized.

WordPress image optimization plugin in the media library

You can compress images from the media library. To see the CheetahO image optimizer options, switch the image list to the classic view, like in the image below:


Choose the image you want to optimize and click on the button “Optimize this image”:

When the image is optimized, you will see the optimization statistic instead of the button “Optimize This Image”. Want to optimize more than one image?

  • Select more than one.
  • In the field “Bulk actions” choose “Optimize all with CheetahO”.
  • Click the button “Apply”

Bulk image optimization (compression) for WordPress

Remember: Do not close the window or go to another page while the system optimizes the images. 

Image backups

The CheetahO WordPress image compression and optimization plugin allows you to make backups of images before you optimize them. You can disable this feature in the plugin settings page, but we highly recommend you use backups. If the system cannot optimize images or there’s an error, you can always restore the original images from backups (by clicking the “Reset” button near the image). When all the images are optimized and you are happy with the results,  you can empty the backup folder by clicking just one button in the CheetahO plugin settings page (“Empty backups”).

Will the WordPress plugin work on a localhost?

Unfortunately, the CheetahO image optimization/resize plugin only works with publicly accessible websites. If your site is locally hosted, this means that it is not publicly accessible. Therefore CheetahO will not be able to download the images to optimize them.
