Case Converter

Just paste or type some text in the box and hit any of the buttons to convert the letter case. As simple as that!

You can then copy the result to the clipboard.

• Sentence case. - capitalize the first letter of each sentence
• UPPER CASE - all letters are converted into capital letters
• lower case - the exact opposite of the one above
• Capitalized Case - the first letter of each word is turned into a capital letter
• AlTeRnAtInG CaSe - first character = upper case, second character = lower case, third character = upper case, fourth character = lower case and so on
• tOGGLE CASE - just inverse letter case: if a letter was in lower case turn it into upper case, if it was in upper case turn it into lower case.
• rANdoM caSE - decide on letter case at random for each character
• Copy to clipboard - that button doesn't change letter case, just copies all the text to the clipboard

There is no hard limit on the input text size.

You can resize the text box by dragging its bottom right corner.
