Case Converter

8 case styles

Type or paste your text, then pick a case style. The converted result appears below, ready to copy.

How the case converter works

Type or paste your text, then click any of the eight case styles. UPPERCASE and lowercase simply change letter casing; Title Case and Sentence case follow standard English capitalization rules; camelCase, PascalCase, snake_case, and kebab-case are common programming naming conventions that strip spaces and punctuation, rejoining words in the chosen style.

Everything happens locally in your browser using plain JavaScript — there's no upload, no account, and no server involved at any point. Close the tab and your text is gone.

When each case style is used

Sentence case and Title Case are common for headings and article titles. UPPERCASE is often used for emphasis, acronyms, or legal document headers, though overusing it in body text reads as shouting. camelCase and snake_case are conventions from programming — variable and file naming — rather than natural writing, so you'll mostly need those when working with code or data files rather than prose.

Frequently asked questions

Title Case capitalizes the first letter of every major word (common in headlines and titles), while Sentence case only capitalizes the first letter of the sentence, like normal prose.

camelCase joins words without spaces and capitalizes every word after the first (e.g. firstName, totalAmount). It's a common naming convention for variables in JavaScript, Java, and many other programming languages.

snake_case joins words with underscores (my_variable_name) and is common in Python and database column names. kebab-case joins words with hyphens (my-variable-name) and is common in URLs and CSS class names.

Standard title case rules typically keep short articles, conjunctions, and prepositions ("the," "of," "and") lowercase unless they're the first or last word — this tool follows that convention rather than capitalizing every single word.

No — case conversion only affects letters; numbers, punctuation, and spacing are left exactly as you entered them.
