Frequently Asked Questions
What is Title Case?
Title Case capitalises the first letter of every major word, following standard English headline rules. It's used for headings, titles, and book names.
What is camelCase used for?
camelCase joins words without spaces and capitalises each word after the first — e.g. myVariableName. It's the standard naming convention in JavaScript, Java, and many other languages.
What is the difference between snake_case and kebab-case?
Both use lowercase words separated by a delimiter. snake_case uses underscores (used in Python and databases), while kebab-case uses hyphens (used in URLs and CSS class names).

Yes, completely free with no sign-up. Paste your text and convert it instantly in any browser.
