Convert text to UPPERCASE, lowercase, Title Case, Sentence case, camelCase, PascalCase, snake_case, or kebab-case instantly. Nothing you type here is ever sent anywhere.
Type or paste your text, then pick a case style. The converted result appears below, ready to copy.
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.

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.
