What is a case converter?

The Case Converter transforms text between different letter cases instantly — uppercase (ALL CAPS), lowercase (all small), title case (Every Word Capitalised), sentence case (Only first word capitalised), camelCase (likeThisForCode), snake_case (like_this), and kebab-case (like-this).

Case conversion is essential for developers (variable naming conventions), writers (headline formatting), and data processors (normalising text for databases or APIs). This tool handles all common case formats with a single click.

Why use a case converter?

Manually converting text case is tedious and error-prone for long passages. Whether you're formatting a headline, cleaning data, or converting variable names between coding conventions, a case converter saves time and ensures consistency across your content or codebase.

What is title case?

Title case capitalises the first letter of every major word. Small words like 'a', 'an', 'the', 'and', 'but', 'or' are not capitalised unless they start the title.

What is camelCase used for?

camelCase is a programming convention where words are joined together with the first word lowercase and subsequent words capitalised (e.g., myVariableName). It's standard in JavaScript, Java, and many other languages.

What is snake_case?

snake_case joins words with underscores and uses all lowercase (e.g., my_variable_name). It's standard in Python, Ruby, and SQL.

What is kebab-case?

kebab-case joins words with hyphens and uses all lowercase (e.g., my-variable-name). It's used for HTML class names, CSS properties, and URL slugs.

Does this work for languages other than English?

The basic upper/lowercase conversions work for most Latin-script languages. Title case capitalisation rules are optimised for English — other languages may have different capitalisation conventions.
