How to change the case of text

1. Paste or type your text into the box.
2. Click one of the buttons: UPPERCASE, lowercase, Title Case or Sentence case.
3. Check the result and press Copy. Your original text stays unchanged in the input box, so you can try another style.

The four styles

• UPPERCASE — EVERY LETTER IS A CAPITAL. Used for short labels, warnings and acronyms. Long passages in capitals are harder to read.
• lowercase — every letter is small. Handy for cleaning up text before further editing, for tags and for email addresses.
• Title Case — The First Letter Of Every Word Is Capitalised. Used for headings, book titles and product names.
• Sentence case — Only the first letter of each sentence is capitalised. This is how normal text and many modern headlines are written.

Good to know

Title Case in this tool capitalises every word. Style guides such as AP or Chicago keep short words like “and”, “of” or “the” in lowercase in the middle of a title, so you may want to adjust a few words by hand. Sentence case lowercases everything first, so proper nouns and acronyms (for example “London” or “PDF”) need to be capitalised again afterwards.

The most common use is fixing text that was typed with Caps Lock switched on: paste it, choose Sentence case and copy it back. The conversion works with accented letters and other alphabets as well.
