Using full-sized images on your WordPress site not only takes up storage space but slows down your site, too. Instead of wasting time and effort compressing them manually, see how Smush can help you do it in bulk.
Smush is an award-winning image optimization plugin that focuses on compressing and resizing your images. It saves storage space and takes some of the load away from your server, which can speed up your site.
You can manually compress your images before adding them to WordPress but this is a lot more time consuming than simply using a plugin like Smush.
