Transform Text CaseInstantly, in 19 Different Ways

Our text case converter runs entirely in your browser using JavaScript. When you type or paste text, it applies the selected case transformation locally — no data is ever sent to any server. With Auto Convert enabled (on by default), the result updates in real-time as you switch between the 19 different tabs. You can choose from 14 case conversions like UPPERCASE, lowercase, camelCase, snake_case, and 5 utility operations like removing extra spaces and sorting lines.

We support 19 total operations: 14 case styles and 5 utilities. Case styles include: UPPERCASE, lowercase, Title Case, Sentence case, Capitalize Each Word, tOGGLE cASE, camelCase, PascalCase, snake_case, kebab-case, Train-Case, dot.case, path/case, and CONSTANT_CASE. Utility operations include: Remove Extra Spaces, Trim Lines, Sort Lines, Reverse Text, and Reverse Words.

camelCase makes the first word lowercase and capitalizes subsequent words with no spaces (e.g., "myVariableName"). PascalCase capitalizes every word with no spaces (e.g., "MyClassName"). camelCase is commonly used for variable and function names in JavaScript, Java, and TypeScript, while PascalCase is used for class names and React components.

snake_case uses underscores between words (e.g., "my_variable_name") and is standard in Python, Ruby, and SQL databases. kebab-case uses hyphens (e.g., "my-variable-name") and is the standard for CSS class names, HTML attributes, and URL slugs. Both are lowercase-only by convention. Use snake_case for Python/Ruby code, and kebab-case for web development.

Yes. Our Title Case converter follows AP/Chicago style rules: it capitalizes the first and last word, plus all major words. Articles (a, an, the), coordinating conjunctions (and, but, or), and short prepositions (in, on, at, to, for) remain lowercase — unless they are the first or last word. This gives you publication-ready title casing.

Toggle case inverts the case of every single character in your text. Uppercase letters become lowercase, and lowercase letters become uppercase. For example, "Hello World" becomes "hELLO wORLD". This is useful for fixing text that was accidentally typed with Caps Lock on, or for creating stylized text effects.

Absolutely. Every transformation happens entirely in your browser using client-side JavaScript. Your text is never uploaded, transmitted, or stored on any server. We do not track, log, or save any of your content. The only storage is the optional auto-save feature that saves to your browser's localStorage — which stays on your device.

Yes. Once the Text Case Converter page loads in your browser, you can disconnect from the internet and continue using all 19 transformations. Every operation runs locally with zero network requests. This makes it perfect for working on planes, in areas with poor connectivity, or anywhere you need privacy.
