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?
Try it like this:
This one has a loop built into it, make sure you set 'Timed' to 1 second and the 'Format' of the 'Add Date or Time' step to Hour Minute Second
This is known issue with the current release of Safari.
But pasting images from the clipboard is now working properly in the Safari Technology Preview which means the fix should be coming to the public release version of Safari shortly.
FYI, You can go ahead and use the tech preview version alongside your regular Safari install without disrupting anything.
EDIT: Safari 10.1 was released today and fixes this issue.
EDIT #2: It seems to only work with some source applications but not others. For example, I can select and copy sections of web pages w/images and paste them into Gmail no problem (Safari to Safari). I can also copy text+images from Evernote to Gmail. But... the same doesn't seem to work when TextEdit or Notes is the source.

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