Case Converter

Paste your text, pick a case, and it converts instantly in the box below. Select part of the text to convert only that part.

For writing

For code & web addresses (converted line by line)

Everything is converted locally in your browser. Your text is never sent anywhere. Title Case keeps small words (of, the, and, to…) lowercase except at the start and end. Title and Sentence case lowercase the text first, so names and acronyms need re-capitalising (or tick "Keep ALL-CAPS words"). The code cases treat each run of letters and numbers as a word and ignore punctuation.

About this tool

Case Converter changes the capital letters in a piece of text in one click. Turn a block of capitals into normal sentences, make a heading Title Case, or force everything to lowercase before you paste it somewhere else.

It saves the tedious job of retyping text that was typed with Caps Lock on, or tidying a list of names or headings.

How to use it

  1. Paste or type your text into the box.
  2. Choose the style you want: UPPERCASE, lowercase, Title Case or Sentence case.
  3. Check the converted text.
  4. Copy the result and paste it where you need it.

Example

A friend sends you a long paragraph written entirely in capitals. Paste it in, choose Sentence case, and you get normal sentences that start with a capital letter. Then quickly fix any names or abbreviations that should stay in capitals.

Tips

  • After converting to Sentence case or Title Case, scan for names, places and abbreviations such as NASA or JAMB, which may need their capitals put back.
  • Title Case rules vary between style guides. Check the small words (a, of, the) if you are following a particular style.

Questions people ask

What is the difference between Title Case and Sentence case?

Title Case capitalises the main words in a heading. Sentence case capitalises only the first word of each sentence, and proper names.

Will it fix my spelling?

No. It only changes capital and small letters.

Can I convert a long document?

Yes. Paste in as much as you need, within what your browser can handle comfortably.

Is my text stored?

No. The conversion is done in your browser.
