Why screenshots on a Mac?
Screenshots on a Mac are usually very helpful if you want to document an error or if you preserve something from a website for later use. Also, if you create tutorials it is really helpful to create screenshots.
When you are new to the Mac you might have a hard time to find the option to make screenshots and once you’ve done you find that you have the images in PNG format on your harddrive. This is something I really hated because every time I made a screenshot I had to open my Photoshop, cut the picture and save it for web.
Shortcuts for screenshots
You have two options when making screenshots. First of all you can take a picture from the whole screen or, second, you can just take a shot from a detail.
1. Screenshot on a Mac from a whole screen
To make a screenshot from the whole screen press CMD+Shift+3 at once or CMD+Shift+CTRL+3 to add it to your clipboard
2. Screenshot on a Mac from a detail
To make a screenshot from a detail of the screen press CMD+Shift+4 at once and use your left mouse to assign the detail.
To make a screenshot from an open window use CMD+Shift+4+space bar.
Get rid of PNG and save your screenshot on a Mac as JPG
Click on top left on the little magnifier to open your Spotlight and type in “Terminal”. Once done a window pops up with that little program.
Type in (or better copy and paste from here to avoid mistakes):
defaults write com.apple.screencapture type JPG
You can also save it as GIF, then replace JPG with GIF.
Press enter and you are done – screenshots are now saved as JPG (after restart).
If you want to avoid a restart enter
I hope this not-so-common tip helps you to get annoyed because of screenshots 🙂
