What is a Case Converter?

A case converter is a tool that transforms text from one case format to another. Whether you need to convert text to uppercase, lowercase, or any other case style, our free case converter makes it easy and instant with just one click.

Common Text Case Formats

• UPPERCASE: All letters are capital. Commonly used for acronyms and emphasis. Example: HELLO WORLD
• lowercase: All letters are lowercase. Used in domains and programming. Example: hello world
• Title Case: First letter of each word is capitalized. Used in titles and headings. Example: Hello World
• Sentence case: First letter capitalized, rest lowercase. Used in standard sentences. Example: Hello world
• camelCase: First word lowercase, subsequent words capitalized without spaces. Popular in JavaScript and programming. Example: helloWorld
• PascalCase: Similar to camelCase but first letter is also capitalized. Used in class names and many programming languages. Example: HelloWorld
• snake_case: Words separated by underscores, all lowercase. Standard in Python and databases. Example: hello_world
• kebab-case: Words separated by hyphens, all lowercase. Common in URLs and CSS classes. Example: hello-world
• CONSTANT_CASE: Words separated by underscores, all uppercase. Used for constants in programming. Example: HELLO_WORLD
• Alternating Case: Letters alternate between uppercase and lowercase. Example: HeLoWoRlD
• Inverse Case: Swaps the case of each letter. Uppercase becomes lowercase and vice versa. Example: hELLO wORLD

When to Use Each Case Format

Developers: Use camelCase for JavaScript variables, PascalCase for class names, snake_case for Python variables, and kebab-case for CSS classes and HTML attributes.

Writers and Content Creators: Use Title Case for headlines, Sentence case for regular text, and UPPERCASE for emphasis or acronyms.

Database Administrators: Use snake_case or kebab-case for database column names and table names for consistency and readability.
