How to resize a screenshot image on a Mac so that it is "regular size" when posted on the Internet? [duplicate]
Solution 1:
I'm not quite sure what you mean. I tested it with a screenshot (see above) and reduced the resolution to half, uploaded it here, it's still the new resolution that I chose in Preview.
Maybe you can try the following:
- Change the resolution in Preview
- Close the image
- Right click on it, check Get Info, then "More Info", there you should find the current resolution which should be slower than before
- If this does not work for you, maybe try a tool like ImageMagick that offers a lot of options for manipulating images.
