PNG files are blurry

I finally found the problem.

Somehow it didn’t do nearest neighbor.
After i switched it back and forth once.
Now images come out crisp as a potatoe chip.

Really weird. Because before i did that, only images that i scaled up to like 1000% were okay.
This is an original version with a 32 pixel base.

Thanks for the help anyways :D. This is way more fun then i tought it would be. Kinda addiciting, makeing your own tiles. Pretty basic but im still just messing around with it.
