What is Case Converter?

Case Converter is an online tool that simplifies the process of changing the case of your text. This tool provides a quick and efficient way to convert your text into different case styles. Whether you need text in Sentence case, UPPERCASE, Title Case, or even an unusual format like aLtErNaTiNg cAsE, Case Converter has you covered.

The Available Options

1. Sentence case

Sentence case is a commonly used format where the first letter of a sentence is capitalized, and the rest of the sentence is in lowercase. This is the default style for many written documents.


  • Input: "the quick brown fox jumps over the lazy dog."
  • Output: "The quick brown fox jumps over the lazy dog."

2. Lowercase

In lowercase, all letters are converted to their lowercase forms. This is useful when you want to simplify your text or when specific requirements call for lowercase letters.


  • Input: "HELLO WORLD"
  • Output: "hello world"


UPPERCASE, as the name suggests, converts all letters to their uppercase form. It's often used for titles, acronyms, or emphasizing text.


  • Input: "this is uppercase"

4. Capitalized Case

Capitalized Case, also known as Title Case, capitalizes the first letter of every word. This style is common in headings, titles, and proper nouns.


  • Input: "welcome to the world of text formatting"
  • Output: "Welcome To The World Of Text Formatting"

5. aLtErNaTiNg cAsE

The aLtErNaTiNg cAsE style is a playful one. It alternates between uppercase and lowercase letters, creating a visually distinct and unique text.


  • Input: "this is alternating case"
  • Output: "ThIs Is AlTeRnAtInG CaSe"

6. InVeRsE CaSe

InVeRsE CaSe takes the opposite approach. It inverts the case of each letter, turning uppercase into lowercase and vice versa.


  • Input: "tHIS IS iNVERSE cASE"
  • Output: "This is Inverse Case"
