About the Case Converter

Case Converter switches any text between the letter cases writers and programmers actually use: UPPER and lower case, Title Case and Sentence case for headlines, plus camelCase, PascalCase, snake_case and kebab-case for code.

It is ideal for fixing accidentally-typed-WITH-caps-lock text, formatting titles consistently, or preparing identifiers for a programming style guide. Conversion runs entirely in your browser, so sensitive text never leaves your machine.

How to use the Case Converter

  1. Paste your text into the input box.
  2. Click the case you want — the converted text appears immediately.
  3. Use the copy button to grab the result, or keep clicking cases to preview alternatives.

Frequently asked questions

What is the difference between Title Case and Sentence case?

Title Case Capitalizes The First Letter Of Every Significant Word, while Sentence case only capitalizes the first letter of each sentence.

When would I use snake_case or kebab-case?

snake_case is standard for Python variables and database column names; kebab-case (hyphen-case) is the convention for CSS classes, URLs and file names.

Does it handle accented characters?

Yes — the converter is Unicode-aware and correctly transforms accented letters like é, ñ and ü.
