Free Online Case Converter
Convert text between uppercase, lowercase, title case, sentence case, camelCase, PascalCase, snake_case, and kebab-case with this free online case converter. Paste any text and click a button to transform it instantly — no manual retyping needed. Title case follows standard capitalization rules, lowercasing articles and prepositions while capitalizing major words, which is exactly what you need for headlines and blog post titles. Sentence case capitalizes only the first word and proper nouns, matching the style most editorial guides recommend for body text. The programming-oriented formats — camelCase, PascalCase, snake_case, and kebab-case — are essential for developers renaming variables, converting between naming conventions across languages, or generating CSS class names from plain English. Each conversion preserves your original text in the input area so you can try multiple formats without retyping. The tool is useful for copywriters standardizing headline styles, developers converting between naming conventions, students formatting paper titles, and anyone who accidentally left caps lock on. All processing runs entirely in your browser with no data sent to any server. Results update with a single click and can be copied to your clipboard instantly.
Frequently Asked Questions
Title case capitalizes the first letter of each major word. Small words like 'the', 'a', 'in', 'of', and 'and' are typically not capitalized unless they're the first or last word.
camelCase joins words together with no spaces, capitalizing the first letter of each word except the first. It's commonly used in programming for variable and function names (e.g., 'myVariableName').
Uppercase is typically used for acronyms, headings that need emphasis, constants in programming, or short phrases that need to stand out. Avoid using it for long paragraphs as it reduces readability.
snake_case joins words with underscores and uses all lowercase letters. It's the standard naming convention in Python for variables and functions, and is also used in database column names and file naming (e.g., 'my_variable_name').
camelCase starts with a lowercase letter and capitalizes subsequent words (e.g., 'myFunction'). PascalCase capitalizes every word including the first (e.g., 'MyFunction'). In most languages, camelCase is used for variables and functions, while PascalCase is used for class names and components.
