What is the Case Converter?

The Text Case Converter is a free web tool that allows you to easily change the case of any text snippet. Whether you need to convert a paragraph to all uppercase, format a variable for coding (like camelCase or snake_case), or simply clean up some haphazardly typed notes, our converter handles it all in a single click.

Supported Case Types

Standard Cases

  • Lowercase: Converts all characters to small letters.
  • Uppercase: Converts all characters to capital letters.
  • Title Case: Capitalizes the start of every word.
  • Sentence Case: Capitalizes only the first letter of each sentence.

Programming Cases

  • camelCase: First word lowercase, subsequent words capitalized.
  • PascalCase: Every word capitalized, no spaces.
  • snake_case: Lowercase words joined by underscores.
  • kebab-case: Lowercase words joined by hyphens.

Frequently Asked Questions

1. What is the difference between Title Case and Capitalized Case?

Title Case capitalizes every word except for certain minor words (articles, prepositions, etc., though our basic version capitalizes all). Capitalized Case usually refers to starting just the first word with a capital letter, or every word depending on the context. Our Title Case tool ensures the first letter of each word is capitalized.

2. Is there a limit to how much text I can convert?

There is no strict character limit for our web tool, but for extremely large documents (several megabytes), your browser's performance might be affected. It is best suited for snippets, articles, and code blocks.

3. Are my text snippets private?

Yes. Our Case Converter runs entirely in your browser. We do not transmit your text to our servers, and we do not store any of the content you paste here. Your privacy is our priority.

4. Does this tool support special characters and different languages?

Yes, the tool supports Unicode characters, meaning it works well with accented letters and various non-English languages. However, case conversion logic (like Upper to Lower) primarily applies to alphabets that have distinct cases (Latin, Cyrillic, Greek, etc.).
