I have set Command + Shift + 4 to a keyboard shortcut to take a screenshot and save to clipboard, usually, I will paste this image for next usage.

But I want to lower the resolution of the image in the current clipboard because it's too big, how to do this?

enter image description here

  • Is it the resolution specifically you wish to be lower or are you looking for the size of the file it would create to be smaller? – CJK Apr 23 at 17:28
  • In addition you what CJK asked in his comment, are you looking for an automated solution or is the answer given by ankii what your are looking for? If an automated solution, then please be explicit and specific about what you mean by "But I want to lower the resolution of the image in the current clipboard because it's too big". – user3439894 Apr 23 at 17:34
  • hi,answer given by ankii is what I want, but I want an automation method , so I can paste a lower resolution image immediately – user956609 Apr 27 at 6:29
  • With the image at Clipboard, you can open Preview.app, hit command+N.

  • Go to Tools menu > Adjust Size..., make modifications.

  • Using the selection, cover the whole image, liberally. Don't worry if you've got lot of padding around it.

    enter image description here

  • Hit command+C and paste wherever you want.

"Export as..." also provides some options to downsize the image.

  • hi,is there any automation method to do this? – user956609 Apr 27 at 6:29
  • You can make a automator workflow to do so, but most of it is already present in the form of shortcuts like cmd + N, cmd + A, cmd + C. you can look into command Line tools that can do such stuff.. I think brew would have something for that. – anki Apr 27 at 6:39
  • there's no shortcut to adjust width and height – user956609 Apr 27 at 6:47
  • You can see the save as JPG which is a bit straightforward. i.stack.imgur.com/9wm4b.png – anki Apr 27 at 7:15
  • I don't want to save a picture I want a lower res image in the clipboard(not data size, just resolution) – user956609 Apr 27 at 8:57
