The Importance of Web Performance
Speed is a direct ranking factor for Google. Images often make up the bulk of a web page's total size.
Modern Formats: WebP and AVIF
Whenever possible, use modern image formats. They provide superior compression compared to JPG and PNG.
Dimensions and Aspect Ratio
Never serve an image that is larger than the container it will be displayed in. Use our Image Resizer to set the correct dimensions before uploading to your site.
