Transform resize with no anti-aliasing: How to resize layer/image without anti-aliasing in Photoshop?

There are two ways to resize a layer or image in Photoshop without anti-aliasing.

Method 1:

1. Go to the Edit menu in Photoshop -> Preferences -> General. Or press Ctrl+K

2. The third drop-down menu from the top is called Image Interpolation. The drop-down will most likely be set to Bicubic or Bilinear. Change it to Nearest Neighbor.

3. Transforming will now no longer use anti-aliasing. To turn anti-aliasing back on, go back to General Preferences and change the Image Interpolation back to Bicubic.

Method 2:

1. Zoom in on the area that you want to enlarge without anti-aliasing until it is the size that you want it to be in screen pixels (e.g. zoom in 2-3 times)

2. Press the Print Screen key in Windows, or use a screen capture utility on the Mac

3. Paste the print screen image, then crop it

That's it! Done--
