macos Default Filetype

Taking screenshots is the best way to share with your colleagues, IT support staff who can help you fix a problem on your computer or share on social media networks like Facebook, Twitter, Instagram,…

macOS systems will save screenshots as PNG files by default. This is good if you want the image to have high quality, but the disadvantage is that PNG screenshots files often be big in size.

Although you may open the png file by using Preview app, or the third-party image editor, there is still the command line which will help you to save a screenshot as the image format you want.
