How to Use the Case Converter

Enter your text in the input field above and click the desired case conversion button. The tool will instantly convert your text to the selected case, whether it's lowercase, uppercase, title case, sentence case, or others. Once the conversion is complete, you can copy and paste the converted result wherever it's needed.

Convert Text Between:

Sentence Case

Transforms your text so that the first letter of each sentence is capitalized, along with the pronoun "I", making it perfect for polished, professional documents.

Title Case

Capitalizes the first letter of each word, excluding common stop words such as 'and', 'at', etc., ideal for headers and titles.

Capital Case (also known as Proper Case)

Capital Case, or Proper Case, capitalizes the first letter of every word, offering another option for emphasizing headings or titles. Both terms 'Capital Case' and 'Proper Case' refer to the same formatting style, where the initial character of each word is made uppercase, making it ideal for titles, headings, and emphasizing specific text.

Lower Case

Converts all characters in your text to lower case, useful for uniform text appearance.

Upper Case

Transforms all characters in your text to upper case, great for attention-grabbing statements or acronyms.
