I am trying to change resolution in Photoshop but no changes appear. No change to size. For example I set resolution to 300 or even 1 but the size remains as before. It worked well before. Is there an option that turned off?

I'm guessing you have "Resample Image" unchecked.

Your image resolution (PPI) in and of itself is only meta-data, it doesn't actually affect the size of your image. If you actually want to change the size of your image, not only it's PPI value, then you need to resample the image.

enter image description here

Note, your "Image Size" dialog may look different, I believe it changed in CC, I still use CS6—but the option will be the same (or similar).

  • should i set re-sampling mode to nearest neighbors?

  • Depends what you want. Nearest neighbor will give you hard jagged edges, you most likely want one of the "Bicubic" options.
