Selling on Salla? Compress every product image without downloading or re-uploading
Instead of downloading your product images, compressing them here and uploading them again one by one, the RankX SEO app does it inside your store: it finds the heavy images, compresses them, replaces them on the product itself and shows how much you saved.
