Case Converter

How Does the Case Converter Work?

Our case converter tool lets you instantly transform any text into different case formats. Simply paste your text, click the desired case style, and copy the result. All processing happens in your browser — your text is never sent to any server.

Available Case Formats

• UPPERCASE — Converts all letters to capital letters
• lowercase — Converts all letters to small letters
• Title Case — Capitalizes the first letter of every word
• Sentence case — Capitalizes only the first letter of each sentence
• camelCase — Joins words with first word lowercase, rest capitalized (used in JavaScript)
• PascalCase — Like camelCase but first word is also capitalized (used in C#, Java classes)
• snake_case — Joins words with underscores, all lowercase (used in Python, Ruby)
• kebab-case — Joins words with hyphens, all lowercase (used in CSS, URLs)
• CONSTANT_CASE — Joins words with underscores, all uppercase (used for constants)
• dot.case — Joins words with dots, all lowercase (used in config files)
• aLtErNaTiNg CaSe — Alternates between lower and upper case letters
• iNVERSE cASE — Swaps the case of every letter
