Available Case Conversions
- UPPERCASE: Converts all letters to capital letters. Useful for headings, acronyms, or emphasizing text.
- lowercase: Converts all letters to small letters. Often used for normalizing user input or preparing text for comparison.
- Title Case: Capitalizes the first letter of each word. Ideal for headings, titles, and proper nouns.
- Sentence case: Capitalizes only the first letter of each sentence while making everything else lowercase. This is the standard for body text and everyday writing.
- camelCase: Joins words together with no spaces, capitalizing the first letter of each word except the first. Commonly used in JavaScript and other programming languages for variable names.
- snake_case: Replaces spaces with underscores and lowercases everything. Popular in Python, Ruby, and database column names.
- kebab-case: Replaces spaces with hyphens and lowercases everything. Widely used in URLs, CSS class names, and file names.
Why Use a Case Converter?
Manually re-typing text in a different case is tedious and error-prone. A case converter saves time and ensures consistency, whether you are formatting a document, naming variables in code, or preparing content for a website. Developers frequently switch between camelCase, snake_case, and kebab-case depending on the language or framework they are working in.
Frequently Asked Questions
Does this work with special characters and numbers?
Yes. Numbers and special characters are preserved as-is during conversion. Only alphabetic characters are affected by case changes. For programmer cases like camelCase and snake_case, non-alphanumeric characters are treated as word separators.
Is my text stored anywhere?
No. All conversions happen entirely in your browser. Your text is never sent to a server or stored anywhere.
