Change the default resolution of Screen Shots?

The Terminal based screencapture utility does not offer an option to set the capture resolution, only dimensions. Thus I doubt one will have the ability to set a default resolution in screen captures invoked with the keyboard shortcuts either.

I realize this is a slightly older thread, but I also noticed the 72 instead of 144dpi in Sonoma... This might help:

Another discussion said if you keep Floating Thumbnail enabled, it keeps 144dpi. That seemed to work for me.

[Press Shift+Command+5 and choose Options dropdown near the bottom of the screen to enable "Show Floating Thumbnail"; I had this turned off, since I don't like the preview. (I usually use Shift+Command+4 for Screenshots.)]

Otherwise, adding @2x at the end of the file name will also make it show as Retina... E.g. Screenshot@2x.png

Thanks. I already know how to change the resolution from one to another afterwards.

I see...

from Terminal you can see limitations

defaults read com.apple.screencapture

—changing the format to .heic resolution remains at 72ppi

—changing screen resolution has no effect on screencapture utility ppi

Changing the System settings : Displays categories between Larger text and More space may regulate the resolution of the screen capture, but that is the sharp pencil in the head approach that I would not use myself.

Does anyone know if it's possible using a Terminal command or other means to change the default resolution of screen shots from 72ppi to 144ppi? It was 144dpi in Monterey.

TIA

You can read up on sips —the scriptable image processing system.

144 to 72 seems you could do the inverse(?) for your 72 to 144
