The Case Converter changes the letter case of your text in one click: everything in UPPERCASE or lowercase, Title Case for headlines, Sentence case for normal text, or each word capitalized. It also fixes text typed with Caps Lock on.
Which case to choose
- UPPERCASE — all capital letters, for headings and labels.
- lowercase — all small letters.
- Title Case — major words capitalized, short words such as “of”, “and” and “the” stay lowercase: The Lord of the Rings.
- Sentence case — only the first letter of each sentence is capital.
- Capitalize Each Word — every word starts with a capital letter.
- iNVERSE cASE — swaps capitals and small letters, handy after an accidental Caps Lock.
- aLtErNaTiNg — every other letter capital, for jokes and memes.
How to change the case
- Paste your text in the box.
- Press the case you need. If it is not what you wanted, press Undo.
- Copy the result with the Copy button.
