After installing the plugin, go to Tools > Bulk images to set up the plugin. You can resize single images or groups from media library (mode list).
I've found that most plugins that optimize images duplicate images in new folders creating a superstructure that complicates the entire site. This plugin optimizes the images you have uploaded to your site and overwrites them. The thumbs are also regenerated. If the image is converted to webp or if the name of the image is changed, the system tries to correct the images already published in the articles and pages. However, it is possible to restore at any time. If you have space problems you can always delete the original image that is used for the restore

= What about Bulk image resizer = When you upload an image to wordpress, thumbs are created for the template, but the uploaded image is saved and sometimes used. Bulk image resizer resizes uploaded images to optimize site speed and server space.
Be careful If you remove the original images, The images are overwritten at the size you set, so it's important to make a backup first. They assume no responsibility for any malfunctions or loss of information resulting from the use of the plugin.
