: Erase a single pixel in GIMP I am trying to illustrate in GIMP 2.8 with pixel-perfect precision. The pencil tool allows me to fill in a single pixel without any fuzzy edges or anti-aliasing.

To expand on another's answer, first:


Select the first brush (pixel).
Select a size of 1.
Select hard edge
Set "Dynamics" to "Dynamics off"


That's what I needed in order to get a single-click pixel to transparent/blank eraser.

In the tool options for the eraser:


Select the first brush (pixel).
Select a size of 1.
Select hard edge.
Set Dynamics to Dynamics off


Then the eraser should do what you want.

(Also, do not forget that you need an alpha channel on the respective layer.)
