See every featureReduce the Weight and Not the Quality SEO - image optimizer uses a smart combination of the best optimization and lossy compression algorithms to shrink JPEG, GIF and PNG images to the minimum possible size while keeping the required level of quality.
Heavy product images slow down your website, hurting your conversion rate. ShopZip works silently in the background to solve this. Whenever you upload a new product image, our app intercepts it and runs it through advanced lossless compression. This shrinks the file size while preserving the image quality. You also get a bulk scanner to easily compress all your existing older images.
