I've slowly been getting better at blender but one thing that annoys me a lot is that when i press F12 to render my scene, well, it's all pixelated. Examles:
So this here is something i was testing out, and this is when i press Shift+Z

So that's fine and all but then i go to F12 and i get this:

Now, i have read other peoples posts, and they call say "duplicate" and they all have answers, now honestly it annoys me that none of them have a good answer that actually would aid this. I've read all the things i could find, and some of the "Similar questions" and some people have the same problem as me, but i doubt there is nothing i can do?
TL;DR Want to make my renders not pixelated so i can make the low-poly scenes i've been making better. So i can actually zoom in without seeing pixels.
