Minification and compression play crucial roles in optimizing the performance of WordPress websites. Minification is the process of reducing the size of code files by removing unnecessary characters without affecting their functionality. On the other hand, compression involves decreasing the size of all website files to make them load faster on users’ devices. These processes are essential for improving website loading speed, user experience, efficiency, performance, and search engine optimization (SEO).
