Case Converter — Change Text Case in Your Browser — Tools Star Hub

What this tool does

Switch text among uppercase, lowercase, title case, sentence case, camelCase, PascalCase, snake_case, and kebab-case. Developers renaming identifiers, and editors fixing a headline, can recase a paste in one step. Sentence case follows English punctuation, so it will not apply another language’s capitalization rules.

How to use

  1. Paste text into the box.
  2. Choose a case. The output updates immediately.
  3. Copy the result or clear both boxes.

Examples

  • Title Case

    “hello world” becomes “Hello World”. Each word is capitalized.

  • camelCase

    “Hello world example” becomes helloWorldExample.

How it works

UPPERCASE and lowercase use the English locale. Title Case capitalizes the first letter of each word. Sentence case lowercases the text, then capitalizes the start of the string and letters after . ! ? or … — a simple English-oriented rule, not a grammar checker for every language. camelCase, PascalCase, snake_case and kebab-case are built from letter and number groups.

Limitations

Sentence case follows English punctuation, not the capitalization rules of other languages. camelCase, snake_case, and kebab-case keep letter and number groups and drop the punctuation between them.

FAQ

Is the Case Converter free?
Yes. Switching text among uppercase, lowercase, title case, and the code-style cases is free, with no account.
Does sentence case work in every language?
No. It follows a basic English punctuation pattern. It will not apply language-specific rules.
Is my input sent to a server?
No. The text you paste is recased in this tab. It is not uploaded and not written to local storage.
What is the difference between title case and sentence case?
Title case capitalizes the first letter of each word, as in a headline. Sentence case capitalizes only the first letter of each sentence, as in normal writing.
What are camelCase, snake_case, and kebab-case?
They are naming styles used in code. camelCase joins words with capitals (myVariableName), snake_case uses underscores (my_variable_name), and kebab-case uses hyphens (my-variable-name).
