Not necessarily. It is certainly easier to read a dockerfile, but there are tools like https://github.com/wagoodman/dive (im sure there are others) that allow you to inspect images themselves in a very detailed manner.

…which is focused on the final resulting image size. Dive is a good tool for the latter IME. https://github.com/wagoodman/dive It doesn't do the work for you, but it does single out the big layers in your image.

This app is great for discovering waste https://github.com/wagoodman/dive I've found 100MB fonts and other waste. All the tips are good, but until you actually inspect your images, you won't know why they are so bloated.
