This means your images were not properly scaled for where they are being displayed. Scaling images before uploading them can be time consuming but can save space and speedup load time. First, determine what size your image needs to be. You can use the built-in images size detector included in the free version of Smush to find what height and width your image should be. Once you know how large the image should be, scale your images to the right size.
Tip: If you’re having any issues or want to save a tone of time, The Smush Pro CDN includes auto resizing.
Nope. WordPress crops and resizes every image you upload for embedding on your site. By default, Smush only compresses these cropped and resized images, not your original full-size images. To compress your original full-sized images use Smush Pro.
GIF files are large and can’t be optimized much. They should only be used if the image is animated.
PNG is best for computer generated graphics (vectors, logos, fonts, etc.), images with few colors or images with transparency.
JPG should be used for photography or images with a lot of color variation.
Tip: The Smush Pro CDN includes WebP compression – sharper images that are 25 to 30 percent smaller than JPEG and PNG files.

First, check to see if you’re receiving any server errors. If your images seem to be processing correctly check the file size of the images being skipped. Images over 5mb will be skipped. To compress images up to 32mb get Smush Pro.
Great question! It is important to understand Smush is an optimization tool that uses lossless image compression to save disk storage space and speed up your site. Smush squeezes data from your image files that will save space, resize huge images, and improve speed without changing quality.
You can track file size changes in your media library, individual image savings, directory savings, and Smush total savings with Smush stats. If you want to see some additional magic, run before-and-after page-speed tests with WP Checkup or Google PageSpeed Insights. Every little bit of resource savings is important when it comes to page-speed!
