does anyone know how to fix this? Im using photo pea btw

You should make it as a vector graphic. Then scale it to the max size you intend to view it as before exporting it as an image file. It can always be scaled down without much (if any) distortion but once a graphic is rasterized it can’t be scaled up without distortion. (Pixels can be removed but not added)
