How to change the screenshot file format in OS X
May 18, 2009 by Ross McKillop
This brief tutorial will show you how to change the default file format for screenshot (which is .png) to .jpg, .gif or even .pdf.
- As we outlined in the introduction to Apple Keyboard shortcuts tutorial, taking a screenshot in OS X is as easy as
+
+ 3 (Command+Shift+3, to take a screenshot of the entire screen) or
+
+ 4 (Command+Shift+4, to take a screenshot of a region of the screen). The resulting screenshots will appear on your Desktop as PNG files. - Open up a Terminal by selecting Applications -> Utilities -> Terminal. Enter the following command:
defaults write com.apple.screencapture type PDF
- Now sign out (click the “Apple Button” from the Menu Bar and select Log Out Your Name…. Remember to save all open documents etc before you log out.
- When you sign back in again, take another screenshot. This time it will be a PDF.
- To change formats again replace PDF in the line “defaults write com.apple.screencapture type PDF” to JPG, GIF or PNG to reset it back to the default.
