How to convert PNG to JPG on Mac

Image file formats are all around us, even if we don’t know much about them. Every time we save a photo, icon, or another graphic to our Macs, it has a specific file format, which gives it certain advantages but also restrictions.

JPEG (or JPG) and PNG are two of the most popular image formats. How do you know which one to use and when? And how to convert PNG to JPG on Mac when required by a form you’re filling out, for example?

What’s the difference between JPG and PNG?

When you see a JPG and a PNG image side by side, it’s hard to tell the difference. So what’s the reason behind two different formats?

JPEG (Joint Photographic Experts Group) is a format used primarily for digital images, especially photographs. It can achieve a high degree of compression with minimum effect on quality. As such, JPEG is the most popular image format in the world.

PNG (Portable Network Graphics) supports lossless image compression and was created as a replacement for GIF. One of the key features of PNG is its support for transparent backgrounds. On the other hand, PNG is not used for high-quality printing (due to the lack of support for CMYK) and tends to have larger file sizes.
