About the Case Converter

The Case Converter changes the capitalisation of any text in one click. Turn a paragraph into UPPERCASE, lowercase, Title Case or Sentence case without retyping it. It is useful for fixing text typed with Caps Lock on, formatting headings, cleaning up copied content and preparing text for documents or social posts.

How to use the Case Converter

1. Paste or type your text into the box.
2. Choose UPPERCASE, lowercase, Title Case or Sentence case.
3. Copy the converted text, or press Clear to start again.

Frequently asked questions

Is my text saved anywhere?

No. The conversion runs in your browser and your text is not sent to a server.

What is the difference between Title Case and Sentence case?

Title Case capitalises the first letter of every word. Sentence case capitalises only the first letter of each sentence.

How the Case Converter works

Paste your text and press one of the buttons to change it in place. UPPERCASE and lowercase change every letter. Title Case makes the first letter of every word a capital. Sentence Case makes everything lowercase and then capitalises the first letter of each sentence.

The conversion happens in your browser and is instant. Use Clear to empty the box.

Worked examples

Input: the quick brown fox. it jumps over the lazy dog!

• Sentence Case: The quick brown fox. It jumps over the lazy dog!

Tips and common mistakes

• Title Case here capitalises every word, including small words such as "of" and "the". Style guides often keep those in lowercase, so edit them if needed.
• Sentence Case converts everything to lowercase first, so names, acronyms and the word "I" need to be capitalised again by hand.
• Use lowercase for email addresses, usernames and URLs, as many systems treat them as case-insensitive.
• Use UPPERCASE sparingly. Large blocks of capital letters are harder to read.

More questions about the Case Converter

Can I undo a conversion?

There is no undo button, so copy your original text somewhere safe before you convert it.

Does it work with Hindi?

Hindi has no uppercase or lowercase, so the buttons will not change Devanagari characters.

Why does Title Case capitalise "Of" and "The"?

The tool follows a simple rule and capitalises every word. Adjust small words manually if your style guide requires it.

Is my text sent anywhere?

No. The conversion runs entirely in your browser.
