I'm annoyed with this behaviour since forever, so its time to ask: why Photoshop change edges colours when there's clearly absolutely no reason to do so? Here is an example: I'm dealing with the logo from my firm, plain squares, straight pixels.

enter image description here

Its a colorbar in a sofa shape.
As you can see below, the edges are really hard, no smoothing whatsoever.

Now, I want to turn this into a square like this:

enter image description here

Looks almost fine.
But when I zoom in:

enter image description here

I know it is supposed to help optical viewing and stuff, works great for photos, thats the name of the software, ok. But guess what? I don't want that now.

Is there any way of turning this behaviour off?

PS: I have a vector version of the logo and I know how to do that in Illustrator, but I'm asking for a philosophical reason (and for the glory of Satan).

You can specify a default interpolation method to use whenever Photoshop resamples image data. Choose Edit > Preferences > General (Windows) or Photoshop > Preferences > General (Mac OS), and then choose a method from the Image Interpolation Methods menu.

In your case need change to: Nearest Neighbor (Default: Bicubic)

Also possible specify interpolation in resize window in Resample option:

  • Mac OS:

Photoshop Resize GUI MacOS

  • Windows:

If you are using transform techniques like scale or distort, remember to change the interpolation method in the tool options bar:

  • Seemed very promissor, but nothing changed. Same crappy borders. And oddly enough, the preview before applying the changes looks perfect. Commented Nov 21, 2018 at 16:31

    Just realised I must also change the tool preferences. Thank you. Commented Nov 21, 2018 at 16:35
