How do I adjust the sprite in the animator without moving the collider?

Hello, I am new to game development so please bear with my newbie question.

So I've created a bunch of sprite animations for a character in my game, which I have also created their transitions. However while testing the character out, I found the circle collider to not be accurate as I would like them to be. The sprite for my jump animation is higher than the idle state, therefore when I am jumping, the landing seems very weird.

This is the idle state

So I believe what I would like to do is to move the sprites for the jump animation downwards into the circle collider, without actually moving the original settings (from the idle state)
