No it's not! You create your content with text and images, you send it to two friends: one opens it in a 27" inch monitor, the other one on his mobile phone. How big should the images be? How big the text? What happens if there is a text on the left and an images on the right, and you watch it on a mobile phone? should it go down, should the image resize to occupy at maximum half the viewport? what happens when the text overflows?
The reason you can do it on a Oowerpoint or Publisher is that the viewport is the same, you position it and you are done. The user on the desktop will see it very small, the user on the phone will need to keep scrolling and dragging.
If you are ok with these limitations, there are plenty of tools available to share content! You named them.
If you want better control, there are no easy way of doing it, there are no example of this problem being solved, and I don't think it's a web problem.
