What vegans and vegetarians have in common is that none of them(us) eat meat, but the main difference is that vegetarians are consuming dairy products, eggs, wear some animal products like wool, silk leather etc compared to vegans who are avoiding all of that and therefore the Vegetarianism is counted as diet while the Veganism is more like lifestyle. Another important thing about vegans is that they strongly believe that animals should be protected with many laws same as the humans are protected. Below is small comparison chart, which we hope will make things clear.
Veganism is a philosophy and compassionate lifestyle whose adherents seek to exclude the use of animals for food, clothing, or any other purpose. Vegans endeavor not to use or consume animal products of any kind.
