I have a PNG that I want to add additional content to. For this I need to increase the canvas size of the image: Just make the image larger, but without scaling the existing contents (which the Adjust Size tool seems to insist on doing).

How can I do this?

One option would be to press ⌘AX and then ⌘V after resizing the image. The pasted image doesn't seem to get snapped to canvas edges though.

Increasing canvas size by cropping doesn't seem to be possible.

Nice quick and dirty solution. I noticed the quality of my image seemed to drop though, so watch out for that. –  Kyle Sep 6 '14 at 22:16

The best method I have found is:

  1. Take a screenshot that is larger than your image you are working on, I usually take a shot of an empty text document so that it is entirely white.

  2. Paste your image onto the new image, and then add your other pasted image as well.

  3. Select the new combination image and copy it and make a final image by creating a new one from the clipboard.

This method only works if your two or more images are smaller than your screenshot image, but it works 95% of the time for me.
