I guess you are talking about a visible rectangle around the image you loaded. Setting a color key can make that invisible and only image will be displayed. please refer the sample code below.

class player(pygame.sprite.Sprite):
    def __init__(self, filename):
        super().__init__()
       
        self.image = pygame.image.load(filename).convert_alpha()
        self.image.set_colorkey((255, 255, 255))
       
        self.rect = self.image.get_rect()

dont blit it?

Rects are actually invisible. The color comes from the Surface objects which they are a part of. In short, if you create directly using the Rect class, then it will be invisible.
