Exciting update! We've collaborated with Wix to offer WBI users with a free plan for all website creation needs - Explore the details here.
Reducing the file size of your images is the best way to optimize them for web use. You can do this in a program like Photoshop by reducing the number of colors in the image, or by using a tool like ImageOptim to reduce the file size without reducing quality.
Caching means that your web server will save a copy of your website’s files so that they don’t have to be loaded every time a user visits your site. This can speed up loading times for repeat visitors to your site.
To set up caching on your site, you need to add some code to your .htaccess file. For more information on how to do this, see the Wix Help Center.
