How This Case Converter Works
Type or paste your text into the box, then click any of the case buttons below to instantly transform it. The converted text replaces what's in the box, so you can chain conversions or copy the result right away using the "Copy text" button.
Understanding the Case Styles
- UPPERCASE and lowercase. Every letter converted to all capitals or all lowercase.
- Title Case. The first letter of each word capitalized, commonly used for headings and titles.
- Sentence case. Only the first letter of each sentence capitalized, matching normal writing style.
- camelCase and PascalCase. Words joined together with no spaces, used heavily in programming for variable and class names.
- snake_case and kebab-case. Words joined with underscores or hyphens, common in programming, URLs, and file names.
- aLtErNaTiNg CaSe. Letters alternating between uppercase and lowercase, often used for stylized or sarcastic text.
Who This Tool Is For
Developers naming variables and functions consistently, writers fixing capitalization in titles and headings, and anyone who needs to quickly reformat text between different case styles without retyping it by hand.
Frequently Asked Questions
Is this case converter free to use?
Yes, completely free with no limit on how much text you can convert, and no account is required.
Does this tool store or send my text anywhere?
No. Everything happens directly in your browser using JavaScript. Nothing you type or paste is sent to a server or saved anywhere.
What's the difference between camelCase and PascalCase?
camelCase starts with a lowercase letter, such as firstName, while PascalCase starts with an uppercase letter, such as FirstName. Both remove spaces and capitalize the start of each subsequent word.
Can I convert the same text multiple times?
Yes. Each button converts whatever is currently in the text box, so you can apply one case style and then try another without needing to retype anything.
