The extension works when uploading images in the OpenCart File Manager. ShortPixel uses advanced compression algorithms to reduce the file size of images without significantly compromising their quality. This can be beneficial for websites as smaller image files lead to faster page loading times, which is crucial for a positive user experience and can also impact search engine rankings. ShortPixel Image Optimizer seamlessly processes your uploaded images in the background, sending them to ShortPixel's optimization cloud. Robust algorithms optimize and convert the images before downloading and replacing them in your OpenCart File Manager. These optimized images, visually indistinguishable from the original but significantly smaller in file size, are served in place of the heavier ones. This results in faster page loading times and enhances your Core Web Vitals.
