The expression "by far" means that something is by a big margin or greatly superior to everything else. It is typically used to compare two or more things, in which one thing is significantly better than the others. For example, "She is by far the best singer in the competition" means that she is much better than all the other contestants. "This is by far the most delicious pizza I've ever tasted" means that it's significantly better than any other pizza the speaker has had before. It's a simple way to emphasize that something is clearly the best or the most.
