- Title CaseCapitalises each word except short articles, conjunctions, and prepositions, which stay lowercase unless they are first or last.

- Capitalized CaseCapitalises the first letter of every word without exceptions. Useful for names and headings where every word should be raised.

- UPPER CASEEverything uppercase. Readable, but long runs of capitals slow reading down and are often treated as shouting.

Which case should you use?
Most people arrive here with one of three problems: a line typed with caps lock on, a heading that needs to look like a heading, or a name that came out of a spreadsheet in the wrong shape.
- Whole line in capitals — use sentence case. It lowercases everything and then raises the first letter of each sentence.
- Capitals in the wrong places — use inverse case. This is what caps lock plus shift produces, and flipping every letter restores it exactly.
- Headline or article title — use title case, which keeps short linking words lowercase the way published writing does.
- Names, labels, menu items — use capitalized case, so no word is left lowercase.
This tool keeps your text searchable
Changing case produces ordinary letters. That matters, because the Unicode font generators elsewhere on this site do something fundamentally different: they replace each letter with a look-alike character from another Unicode block, which is why styled text is not matched by search and is read incorrectly by screen readers.
If you want text that looks styled, use the fancy text generator and read how Unicode fancy fonts work first. If you want text that stays readable and findable, case conversion is the safe choice.
Frequently asked questions
What is the difference between title case and capitalized case?
Capitalized case raises the first letter of every word without exception. Title case follows writing conventions: short articles, conjunctions, and prepositions such as a, of, and to stay lowercase unless they are the first or last word. Title case is what you want for a headline; capitalized case is what you want for a name.
How do I fix text I typed with caps lock on?
If the whole line is capitals, use sentence case. If the capitals are inverted — lowercase where capitals should be and the reverse — you had caps lock and shift fighting each other, so use inverse case, which flips every letter back.
Does converting case change the characters?
No. The output is ordinary text, so it stays fully searchable and screen readers read it normally. That is the difference between this tool and the Unicode style generators on the rest of the site, which swap letters for look-alike characters.
Why is my sentence case not capitalising every sentence?
Sentence case starts a new sentence after a full stop, question mark, or exclamation mark followed by a space, and after a line break. Sentences separated by a semicolon or a comma are treated as one, because grammatically they are.
What is alternating case used for?
It is the mocking-tone meme, where alternating capitals imply a sarcastic repetition of something someone said. It has no other practical use, and it is hard to read, so keep it to short phrases.
Is there a limit on how much text I can convert?
No. Everything runs in your browser, so nothing is uploaded and there is no length cap beyond what your device can handle comfortably.
