What is the difference between crepes and blintz?

Crepes are thin, delicate pancakes made from a batter of flour, eggs, and milk, typically served flat and can be filled or topped with a variety of sweet or savory ingredients. Blintzes, on the other hand, are a type of filled crepe, usually made with a similar batter but are often filled with a sweet cheese mixture, folded into a rectangular shape, and then pan-fried or baked. While both are versatile and popular in various cuisines, the key difference lies in the preparation and the way they are served.
