Frequently Asked Questions
Common questions about Smush Image Optimization – Optimize Images | Compress & Lazy Load Images | Convert WebP & AVIF | Image CDN
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 speed up 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.
Lazy Load will defer your offscreen images from loading until they are needed. From the Smush Dashboard, select Lazy Load and click Activate. Smush Lazy Load works out of the box or can be customized based on your needs. Tip: If you're having any issues or want to save a ton of time, the Smush Pro CDN includes auto-resizing of images.
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/AVIF compression - sharper images that are 25 to 60 percent smaller than JPEG and PNG files.
Yes! EXIF data stores camera settings, focal length, date, time, and location information in image files. EXIF data makes image files larger, but if you are a photographer you may want to preserve this information. We have included the option to preserve EXIF image data with Smush.
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 not be processed by the free version of Smush. To compress images up to 256mb, get Smush Pro.
Great question! It is important to understand Smush is an image optimization tool that uses lossless image compression to save disk storage space and speed up your site. Smush squeezes data out from your image files that will save space, resize huge images, and improve speed - all 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 Google PageSpeed Insights. Every little bit of resource savings is important when it comes to page-speed!
Optimizing all the image sizes generated by WordPress, images being imported from plugins and themes, and images from other web sites is a painful and time-consuming process. Smush automatically handles optimizing all your images no matter where they come from, and can be used either as a standalone tool or alongside Photoshop.
Yes, Smush can help you serve images in next-gen formats. Smush Pro offers both WebP and AVIF conversion, allowing you to optimize your images for better performance and meet Google PageSpeed recommendations. This feature is exclusive to Smush Pro.
It depends what side of the pond you live on... but whether you say optimize, optimise, optimizer, or Smush goddess of speed, this plugin will make sure your images are loading lightning fast.
