And after some time this leads to a number of files in the database that are not used anywhere on your WordPress website. Moreover, the Media Library can become messy with duplicate files and other files that are no longer used on the website. So, cleaning up your WordPress media library maintains disk space on your hosting server, and decreases backup sizes. That helps you to save your money after hosting space. Uploading smaller size images rather than putting larger images on your Media Library can help you to raise the available space on your web server. It will help to enhance your website speed for both on the front as well as back end.
