Frequently asked questions
What is the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of every word, which suits headlines. Sentence case capitalizes only the first letter of each sentence, which suits body copy and most UI text.
What are camelCase, snake_case, and kebab-case?
They are common formats in code and URLs. camelCase joins words with capitals (myVariableName), snake_case joins them with underscores (my_variable_name), and kebab-case joins them with hyphens (my-page-slug).
Is my text private?
Yes. All conversion happens locally in your browser. Nothing you paste is sent anywhere.
