Is there any way of having an image block on the desktop version, but a text block in the same place on mobile?

I am using an image of text as my H1, primarily because I had it designed in specific colours.

However, due to the rendering, it looks extremely small on the mobile version (see image)

Is there any way of either changing the size on mobile only, or just having a normal text box in it's place on the mobile version?

Thanks

Alex
