is there a way to chane 128x128 into 512?

What do you mean?

no.
128x128 is much less pixels than 512
pixels wont generate themselfs automaticly.

so a 128x128 image will be forever blury on a 512 :c

you can ask an artist to remake it or something like that. and you can get it better with photoshop.

But yes, it'll probably forever be blurry
