We support 11+ case formats including: UPPERCASE, lowercase, Sentence case, Title Case, camelCase, PascalCase, snake_case, kebab-case, dot.case, tOGGLE cASE, and rAnDoM CaSe. Perfect for both writing and programming needs.
camelCase is a naming convention where the first word is lowercase and subsequent words are capitalized without spaces (e.g., myVariableName). It's commonly used in JavaScript, Java, and other programming languages for variable and function names.
camelCase starts with a lowercase letter (myVariableName), while PascalCase starts with an uppercase letter (MyClassName). PascalCase is typically used for class names in programming, while camelCase is used for variables and functions.
snake_case (with underscores) is commonly used in Python, Ruby, and database naming. kebab-case (with hyphens) is popular in URLs, CSS classes, and file names. Both improve readability for multi-word identifiers.
Yes! You can convert multi-line text and paragraphs. The tool preserves line breaks and applies the selected case conversion to all text in the input area.
Your text is only stored locally in your browser for convenience (so you can return to it later). We never send your text to our servers or store it in any database. Your privacy is completely protected.
Toggle Case (tOGGLE cASE) inverts the case of each letter - uppercase becomes lowercase and vice versa. It's useful for fixing text that was typed with Caps Lock on accidentally, or for creative text styling.
