Case Converter transforms your text into any naming convention or case style instantly. Ideal for developers switching between variable naming styles, writers formatting titles, and anyone who needs consistent text casing without manual editing.
camelCase joins words together with no spaces. The first word is lowercase and each subsequent word starts with a capital letter — e.g. myVariableName. It's commonly used for variable and function names in JavaScript, Java, and Swift.
Both separate words with a delimiter instead of spaces. snake_case uses an underscore (my_variable), while kebab-case uses a hyphen (my-variable). Snake case is popular in Python and databases; kebab-case is common in CSS and URLs.
PascalCase (also called UpperCamelCase) capitalizes the first letter of every word with no separators — e.g. MyClassName. It's the standard for class and component names in C#, TypeScript, and PHP.
No. All conversions happen entirely in your browser using JavaScript. Your text never leaves your device and nothing is stored on any server.
CONSTANT_CASE (also called SCREAMING_SNAKE_CASE) uses all capitals with underscores between words — e.g. MAX_RETRY_COUNT. It's the convention for constants and environment variables in most programming languages.
Yes — the tool handles any amount of text, including multiple paragraphs. Cases like UPPERCASE, lowercase, and Sentence case will preserve your line breaks; programmatic cases like camelCase collapse whitespace by design.
Case Converter is a free, browser-based text transformation tool that converts any text into every major case style in a single click. Whether you're a developer switching between naming conventions, a content writer formatting headings, or anyone needing consistent text casing without manual editing — this tool handles it instantly with no sign-up required.
Different programming languages and ecosystems enforce different naming conventions. JavaScript uses camelCase for variables and functions, PascalCase for classes and React components, and CONSTANT_CASE for constants. Python prefers snake_case for functions and variables. CSS and HTML attributes use kebab-case. Switching between these contexts manually is tedious and error-prone — Case Converter makes it a one-click operation.
UPPERCASE converts every character to its capital form. Used for headings, labels, and constants. lowercase does the inverse — every character becomes its small form, useful for email addresses and URL normalization. Title Case capitalizes the first letter of each word, following the standard convention for book titles, article headings, and UI labels.
Sentence case capitalizes only the first word of each sentence, mimicking natural prose. camelCase and PascalCase are the two standard formats for multi-word identifiers in object-oriented and functional programming. snake_case and kebab-case use delimiter characters instead of capitalization to separate words, making them readable in contexts where spaces are not allowed (file names, URLs, CSS class names).
CONSTANT_CASE combines all-caps with underscores — the universal convention for environment variables and compile-time constants. dot.case separates words with periods, used in configuration files and package namespaces. Alternating case and Inverted case are stylistic variants useful for design emphasis or social media aesthetics.
All text transformations happen entirely inside your browser. Your input text is never sent to any server, logged, or stored. This makes Case Converter safe to use with sensitive code, private content, or proprietary data.
