🤔 How Does This Tool Work?

Our Text Case Converter instantly transforms your text using JavaScript string manipulation:

  • UPPERCASE: text.toUpperCase() — every character becomes capital
  • lowercase: text.toLowerCase() — every character becomes small
  • Title Case: First letter of every word capitalised, rest lowercase
  • Sentence case: Only first letter of each sentence capitalised
  • AlTeRnAtInG: Alternates upper and lower for each character

Everything runs locally in your browser — your text is never sent anywhere. The result appears instantly in the preview box below the buttons, and you can copy it with one click.

❓ FAQ
What is Title Case?
Title Case capitalises the first letter of every word. Example: 'the quick brown fox' becomes 'The Quick Brown Fox'. It is commonly used for headings, article titles, and book titles.
What is Sentence case?
Sentence case capitalises only the first letter of the first word in each sentence, and keeps everything else lowercase. Example: 'THE QUICK BROWN FOX' becomes 'The quick brown fox'. Used for normal writing.
What is Alternating case?
Alternating case switches between upper and lower case for each character. Example: 'hello' becomes 'HeLlO'. It is mostly used for fun or aesthetic purposes rather than formal writing!
Can I convert a very long text?
Yes! Our converter handles texts of any length. Just paste your text into the box and click the case button you want. It converts instantly no matter how long the text is.
Is my text stored anywhere?
No! All text conversion happens entirely in your browser. Your text is never sent to our servers. It stays completely private on your device.
