You don't need an account, and you don't have to hunt across many single-purpose sites.

Students, office workers, freelancers, developers and anyone who needs a quick conversion, calculation or file tweak without installing software or creating an account. Because the site is available in 10 languages, it also serves people who prefer to work in their own language.
