You can compress your images to optimize them on The Optimize Images Tab . The images will be sent to our Optimize Image API where they are compressed using various algorithms based on its format of whether Lossy or Lossless compression is configured in the options. Images are optimized using Lossy compression by default since they offer significantly greater filesize savings but Lossless compression ensures there are no degradation in visual quality when optimized.
The optimized images will be saved over the original images so that the file path doesn't have to be modified to load the optimized image and the user can maintain using the optimized images even if JCH Optimize is disabled or uninstalled. The original images are backed up and can be easily restored if you're not satisfied with the optimized images.
If the Next-Gen Images setting is enabled then a WEBP format is
also generated and will be loaded in place of the original format. The WEBP format is
only generated if it provides additional file savings over the optimized image, which is
not the case 100% of the time.
If the original images are restored, the WEBP format will be deleted. If the image is optimized again the newer WEBP image will overwrite the existing one.
