The all caps generator converts text into six cases at once (uppercase, lowercase, title case, sentence case, alternating caps and fullwidth) so you can compare them and copy the one you want. Conversion happens as you type, with a copy button on each result.
How it works
Uppercase and lowercase use locale-aware conversion, which matters for a handful of languages. In Turkish, the uppercase of a dotless i is not I, and locale-aware conversion respects that where the browser locale calls for it.
- Title case capitalises the first letter of every word and lowercases the rest. It does not know which short words to skip, so it capitalises "of" and "the" too.
- Sentence case lowercases everything, then capitalises the first letter after a full stop, question mark or exclamation mark.
- Alternating caps flips case on letters only, so spaces and punctuation do not consume a turn and the pattern stays visually even.
- Fullwidth is not a case change at all: it swaps each letter for its fullwidth Unicode counterpart, which is why the spacing changes.
Examples
A short sentence in six cases
Text
the quick brown fox. it jumped.
Result
THE QUICK BROWN FOX. IT JUMPED. the quick brown fox. it jumped. The Quick Brown Fox. It Jumped. The quick brown fox. It jumped. tHe qUiCk bRoWn fOx. iT jUmPeD.
Sentence case capitalises after the full stop as well as at the start, which is what distinguishes it from simply capitalising the first character.
Title case and short words
Text
the lord of the rings
Result
The Lord Of The Rings
Title case here capitalises every word, including "of" and "the". Editorial title case would lowercase those, but which words to skip depends on the style guide, so the tool does not guess.
Limits worth knowing
Sentence case cannot tell an abbreviation from the end of a sentence, so "Dr. smith arrived" becomes "Dr. Smith arrived", correct here by luck rather than by understanding.
Frequently asked questions
Why does title case capitalise "of" and "the"?
Because there is no single correct list of words to skip. Chicago, AP and MLA all differ on it, and the cutoff for short prepositions varies between three, four and five letters. Capitalising everything is predictable, and correcting two words by hand is quicker than undoing a guess you disagree with.
What is the fullwidth option for?
It replaces each character with its fullwidth Unicode equivalent, which was designed to align Latin letters with CJK character cells. It is now mostly used for a retro or vaporwave look, and the aesthetic font generator has more styles in that vein.
Does alternating caps start with lowercase or uppercase?
Lowercase on the first letter, then it alternates on letters only. Spaces and punctuation do not take a turn, so the visual rhythm stays consistent across words.
Is any text sent to a server?
No. All six conversions run in your browser as you type, so nothing leaves the page, including when you paste something long in.
