How do I convert multiple png to jpg on Mac?

Recently I have some PNG images on my Mac and want to convert PNG to JPG format in batches, but the system's built-in "Preview" application can only convert one at a time, which is too inefficient. I have tried some online conversion tools, but I can only upload a few images at a time, and the conversion quality is not stable.


I heard that there are some scripts or Automator on Mac that can batch convert image formats, but I don't know how to do it specifically, and I'm worried that it will be too complicated. Is there any friend who can share a simple and effective method that allows me to quickly batch convert multiple PNG to JPG on Mac?

Note that PNG has some properties that may make it more versatile and a better choice in some circumstances.

  • Transparency
  • Smaller size for non-photographic images with few colors, like graphs and logos.
  • Pixel perfect reproduction
