Choose the right text case
Sentence case works well for normal prose. Title Case suits headings when your style guide calls for it. Developers often use camelCase in JavaScript, PascalCase for class names, snake_case in Python and kebab-case in URLs. UPPERCASE is useful for short labels and deliberate emphasis.
Private conversion in your browser
The case changer runs locally in the current browser tab. Your pasted text is not uploaded and no account is required. After changing case, use the related uppercase converter, title case converter or text cleanup tools when you need a narrower operation.
