You could change the default system-wide by using a command line in terminal.

Various methods (similar steps, plus mistakes posted in their comments) appear


  1. Notice that the Mac can’t even show a preview of the image, and this is ten years after the image format was introduced. The preview feature unsurprisingly can’t show a preview either: Well ugh. But here’s a surprise: The image on the original Web page is actually a JPEG so a right-click in Chrome to “Save Image As.
  2. Step 1: Press Ctrl and click the image at the same time. Choose the Open With option to load the image into the Preview. Step 2: After editing the image in Preview, like crop, text, and adjustment, you can save photos as JPEG. Step 3: Located to File menu and select the Export button.

Or use one of the features available in the free 'OnyX by Titanium Software' that

allows an 'admin user' to change the defaults back and forth ~ without Terminal.

More often than not I have to capture the screen of my Mac; especially when I’m writing an article and wish to explain some of the points through pictures. I prefer JPEG to PNG (the default screenshot format on macOS) as the former is universally accepted. Hence, I make JPEG default screenshot on my Mac.


{And for occasional changes only, test the idea by making a duplicate of a file

(image) on the desktop and then change its name to something else; and then

add the jpg instead of .png. In several older Mac OS X you can do this OK...}


Some features changed after Snow Leopard 10.6.8 or Mt Lion 10.8.5. The

'Save As' control in the Finder menu is gone -- from sometime back then.


You can open an image in Preview, and sometimes change the file type by

using the Export feature. I seldom use that but happened to notice.


Because my daily use Mac is PPC G4 Mini 1.5GHz Late 2005, with 10.5.8, I

tend to prefer the older systems; but not necessarily the lack of performance.


My newest Mac, a Late 2012 i7 Mac Mini, runs 10.9(.5) Mavericks as shipped.

The 2.3GHz quad-core & dual 1-TB 5400-RPM HDDs is odd match-up w/ slow

spin-rate HDDs as a hardware bottleneck, though 16GB RAM helps some. It

shipped with 'server' software but haven't used it as such. Mostly stock; I did

partition the two factory HDDs so there are four places to install different OS X.

Anyway, simply change the name of an image to .jpg so it no longer uses .png,

and the system will convert it to open as .jpg even if sent somewhere else online.


Or the command line (terminal) can be used. I've OnyX in several Mac OS X.

I've not re-set the default from .png to .jpg in my Mavericks 10.9.5 system.


Too easy for only a few screenshots to change the suffix .png to .jpg. Yet in

my older Mac that runs 10.5.8, I have set the default to .jpg because that's

helpful to edit images on desktop. Also in older Mac, I use ToyViewer editor.

So you have a few choices.


The OnyX is a fairly good kit if you don't want to use Terminal. Or change

the file name/type and the OS X will change the image type, usually.

Maybe it's possible to see if an option appears elsewhere, to Change All.
