Just change the Pixelation H and W in the General properties. When the image gets exported you will have a version at real 1x1 scale.
I mean, a 512x512 image with 4x pixelation will be exported as 128x128 ready to be used in any game,etc... without need to do a resize or whatever to get the real aspect ratio or 1:1 pixels.

I import it into Pixatool and set both pixelation options to 10. If I export, it becomes this:
But I needed the zoomed out version, which is this:
Ah, I think I got it - the original image was just too big. Just had to resize it down a bit and now the pixelation does it job.
Thank for the help!
