What does a case converter do?
It changes the capital letters in your text without retyping it. Sentence case capitalises the first letter of each sentence, Title Case capitalises the main words of a heading (short words such as "and", "of" and "the" stay lowercase unless they come first), and Capitalize Each Word capitalises every word.
For code, camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE turn a phrase into a variable or file name. Everything happens in your browser, so your text is never sent to our server.

Questions
How do I fix text typed with Caps Lock on?
Paste it in and choose Sentence case. Names and acronyms may need a quick manual fix afterwards.
What is the difference between Title Case and Capitalize Each Word?
Title Case keeps short words like "a", "and" and "of" lowercase, as in most style guides. Capitalize Each Word capitalises every word.
Which case should I use for URLs and file names?
kebab-case (words-joined-by-dashes) is the most common for web addresses. snake_case is common for file names and databases.
