About This Tool

A case converter saves you time when you need to change the capitalization of text without retyping it. Whether you accidentally left caps lock on, need to format a headline in Title Case, or want to transform a phrase into a programming-friendly format like camelCase or snake_case, this tool handles it in one click.

Our free case converter supports eight transformation modes: UPPERCASE for emphasis and headings, lowercase for normalizing text, Title Case for headlines and titles, Sentence case for paragraph text, camelCase and PascalCase for variable names in JavaScript and other languages, snake_case for Python and database column names, and kebab-case for URLs and CSS class names. Each conversion is applied instantly with no delay.

The tool runs entirely in your browser and never sends your text to a server. This makes the case converter safe to use with passwords, proprietary code, and confidential documents. There are no usage limits, no accounts to create, and it works on any device with a modern browser.

Frequently Asked Questions

Title Case capitalizes the first letter of every word. It is commonly used for headings, article titles, and book titles. For example, 'the quick brown fox' becomes 'The Quick Brown Fox'.

In camelCase the first word is lowercase and subsequent words start with an uppercase letter (e.g., 'myVariableName'). PascalCase is the same except the first word also starts with an uppercase letter (e.g., 'MyVariableName'). camelCase is common for variables; PascalCase is common for class names.

snake_case uses underscores to separate words and is standard in Python and SQL. kebab-case uses hyphens and is common in URLs, CSS class names, and file naming conventions.

The tool capitalizes the first letter after sentence-ending punctuation (.!?) and at the start of the text. It does not detect proper nouns automatically, so names and places will be lowercase unless they start a sentence.

No. All processing happens locally in your browser. Your text is never transmitted to any server and is not stored or logged.
