Case Converter

Case Converter changes the letter case of your text in one click. Switch between UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case and kebab-case without retyping a single word.

It is built for writers fixing accidental caps-lock, developers renaming variables, and anyone who needs consistent casing across a document. Conversion happens instantly in your browser.

How to use Case Converter

    Type or paste the text you want to reformat into the input box.

  2. 2

    Pick a case

    Choose from seven case styles. The result appears immediately in the output box.

  3. 3

    Copy the result

    Use the Copy button to grab the converted text for your document or code.

The case styles explained

UPPERCASE makes every letter capital, useful for headings or emphasis. lowercase does the opposite. Title Case capitalizes the first letter of each word, the convention for headlines. Sentence case capitalizes only the first letter of each sentence.

Programmer styles reshape spaces too: camelCase joins words with capitalized humps (myVariableName), snake_case joins them with underscores (my_variable_name), and kebab-case joins them with hyphens (my-variable-name).

When developers need case conversion

Naming conventions differ across languages and frameworks. JavaScript favors camelCase for variables, Python prefers snake_case, CSS classes and URLs use kebab-case, and constants are often UPPER_SNAKE_CASE.

Converting between these by hand is error-prone. Pasting a label like "User First Name" and instantly getting userFirstName, user_first_name or user-first-name keeps your code consistent and saves time during refactors.

Frequently asked questions

Can it convert to camelCase and snake_case?
Yes. The converter detects word boundaries from spaces, hyphens and existing casing, then rebuilds the text in camelCase, snake_case or kebab-case.
Will it keep my punctuation?
UPPERCASE, lowercase, Title Case and Sentence case preserve punctuation. The programmer styles strip separators by design to produce valid identifiers.
Is there a length limit?
No. You can convert anything from a single word to a long document.
