Convert text between UPPERCASE, lowercase, Sentence case, Title Case, camelCase, snake_case and kebab-case instantly, then copy the result.
The Case Converter instantly switches text between UPPERCASE, lowercase, Sentence case, Title Case, camelCase, snake_case and kebab-case, which is useful for writers cleaning up copy and developers reformatting variable names or file paths. Paste any block of text and choose the case you need from the available buttons.
Conversion happens live in the browser with no character limit imposed beyond what your device can handle comfortably, and the result is ready to copy straight back out. This avoids manually retyping headlines, renaming variables one at a time, or fixing text that was accidentally typed with caps lock left on.
Sentence and Title Case suit everyday writing and headlines, while camelCase, snake_case and kebab-case cover programming naming conventions, so the one tool serves both writers and developers.
Text typed entirely in capitals by mistake can be converted straight to Sentence case or lowercase in one click, rather than being retyped from scratch.
There is no processing delay or upload step; the case change is applied to the text as soon as you click the button, keeping the workflow fast for repeated edits.
Title Case capitalises each major word, as in "How to Write Better Copy," and is typically used for headings and titles. Sentence case capitalises only the first word and proper nouns, as in "How to write better copy," and matches normal prose formatting.
camelCase (myVariableName) is the convention for JavaScript and Java variables and functions, snake_case (my_variable_name) is common in Python and SQL, and kebab-case (my-variable-name) is standard for URL slugs and CSS class names. Picking the right one keeps code consistent with the surrounding codebase's style.
Sentence and Title Case preserve existing punctuation and only adjust letter casing, while camelCase, snake_case and kebab-case strip spaces and punctuation to build a single continuous identifier. Numbers and existing hyphens or underscores are generally kept as separators during conversion.
Title Case capitalises each major word (How to Write Better Copy); Sentence case capitalises only the first word and proper nouns (How to write better copy).
camelCase for JavaScript variables, PascalCase for classes and React components, snake_case for Python and SQL, and kebab-case for URLs and CSS class names.
