Case Converter

How it works

1. Paste or type your text.
2. Choose a case style.
3. Copy the converted result.

Supported formats & limitations

• Input
  Any plain text, pasted or typed.
• Output
  UPPERCASE, lowercase, Title Case, or Sentence case.

• Title Case capitalizes every word — it doesn’t apply style-guide exceptions for short words like "of" or "the".
• Sentence case detection relies on ., !, and ? to find sentence boundaries.

Frequently asked questions

Is my text sent anywhere? ›

No, conversion happens entirely in your browser as you type.

What does Title Case do exactly? ›

It capitalizes the first letter of every word and lowercases the rest.

Can I convert the result back? ›

Yes, switch to a different case style at any time — the original text in the input box is never modified.

Troubleshooting

Why didn’t my text change? ›

Make sure the text box on the left has content — the output updates automatically once there’s something to convert.

Why does Sentence case capitalize a word mid-sentence? ›

An abbreviation or a decimal number followed by a capital letter can occasionally be mistaken for a new sentence.
