As only 1 image is downloaded, it's OK to make it a big image to show close-up detail. A zoom image is shown when the user clicks to zoom into the spin.Try reducing this to 500-600px for a smaller but still decent size spin. The full-screen images will only load if the user clicks the fullscreen icon on your spin.Typical size is usually 300-400px width but very much depends on the design and layout of your site and the impact you want to make.

You can potentially reduce PNG file size even further with filtering options: If you're serving PNG images, "Optimal" will also enable PNG optimization to slash your PNG image file size by up to 75%. You can specify which format to fall-back to: The format is only supported by Chrome and Opera so Sirv will automatically serve JPEG or PNG equivalents to browsers that don't support WebP. No matter what image format you uploaded, Sirv will process and serve them as WebP if possible.
It supports transparency and alpha too, so is a great alternative to PNG for faster image loading. File size is typically 25-50% smaller than JPEG while keeping the same quality. WebP is usually the most efficient of all web image formats. It's enabled by default, so your images will be served in the most efficient file format (often WebP, if the browser supports it). Sirv automatically does this, with its "Optimal" image format. Image formatīe sure to serve your images in the most appropriate format: JPEG, PNG or WebP.

Reduce your image file size even further by lowering the JPEG/WebP quality below 80%, for example, to 75%. Compare JPEG quality to see what level you find acceptable. Since this reduces image quality, Sirv applies a default of 80% quality - a happy medium between low file size and good quality. Sirv applies JPEG and WebP compression to reduce image file size. With so many images to download, these are the actions you should consider: If you're using 360 degree product views, fast image loading is even more critical.
