Impressed BY or WITH? Which is the correct preposition?

You can use either “impressed by” or “impressed with” in English. There are certain situations where you might choose “by” or “with” but it is usually a personal preference.

You should use “with” when you use the active voice.We also tend to use “with” with “things” and “by” with people but in most cases they are interchangeable.
