Mastering Image Conversion: Switching PNG to JPG on Your Mac

In today's fast-paced digital world, knowing how to efficiently convert images can be invaluable. Whether it’s for saving space, uploading files to a website, or preparing visuals for presentations, converting a PNG to a JPG is often a necessary task. If you're a Mac user, this guide is designed to walk you through the entire process, offering multiple methods to ensure you can convert files with ease and confidence.

  3. Sufficient for Photos: For standard photographs, the quality difference is often negligible.
