Compressing pictures before adding them to PowerPoint is an easy way to reduce file size without compromising on image quality. Use the built-in PowerPoint tools, downloadable add-ins, external services, or photo editing software to find the best compression method for your needs. With the right approach, you can make your PowerPoint presentations faster to load and share without sacrificing aesthetics. A optimized presentation with compressed graphics keeps your audience focused on your message, not waiting for your file.
