Universal Case Converter Privacy: All processing runs locally

How It Works

The Universal Case Converter transforms your text into every popular case format simultaneously. Simply type or paste text into the input field and all eleven case conversions appear instantly below.

This tool supports the following case types:

• UPPERCASE — converts every letter to its capital form.
• lowercase — converts every letter to its small form.
• Title Case — capitalizes the first letter of each word.
• Sentence case — capitalizes only the first letter of each sentence.
• camelCase — removes spaces, lowercases the first word, capitalizes subsequent words. Used in JavaScript and Java variable naming.
• PascalCase — like camelCase but the first word is also capitalized. Used for class names.
• snake_case — replaces spaces with underscores and lowercases everything. Common in Python and Ruby.
• kebab-case — replaces spaces with hyphens and lowercases everything. Used in URLs and CSS class names.
• CONSTANT_CASE — like snake_case but fully uppercased. Used for constants in many programming languages.
• tOGGLE cASE — inverts the case of every character.
• aLtErNaTiNg CaSe — alternates between lowercase and uppercase for each letter.

All processing happens entirely in your browser using JavaScript. Your text is never transmitted to any server, ensuring complete privacy.
