About the case converter
Case mistakes are small but expensive: a heading typed in lowercase, a paragraph pasted from a PDF in ALL CAPS, a product name that should be in Title Case. This converter fixes the case of any text in one click, with seven styles — UPPERCASE, lowercase, Title Case, Sentence case, Capitalise Every Word, aLtErNaTiNg case and iNVERSE case — applied live as you type or paste.
The two styles people confuse are Title Case and Capitalise Every Word. Title Case follows the headline rules used by newspapers and book publishers: the first and last words are capitalised, and short joining words — a, an, the, and, but, or, in, on, of, to — stay lowercase in between. Capitalise Every Word does exactly what it says, with no exceptions, which suits labels, buttons and some house styles. Sentence case is the cleaner for pasted shouting: it lowercases everything, then capitalises the first letter of each sentence.
Everything happens in your browser. The text is converted on your device and never uploaded, and the result can be copied straight to the clipboard or downloaded as a .txt file — useful when the fixed text is heading for a document, a spreadsheet or a content system that would take longer to fix by hand.
Frequently asked questions
Title Case rules, fixing capitals and privacy, answered.
What is the difference between Title Case and Capitalise Every Word?
Title Case keeps small joining words (a, the, and, of, in) lowercase unless they start or end the title — headline style. Capitalise Every Word capitalises every single word, no exceptions.
Can it fix text that is ALL IN CAPS?
Yes. Paste it in, choose Sentence case or lowercase, and the shouting is gone — Sentence case keeps the first letter of each sentence capitalised.
Does it work as I type?
Yes. The converted text updates on every keystroke, and you can switch between the seven styles at any time to compare them.
Is my text uploaded?
No. The conversion runs entirely in your browser, and nothing is stored or sent anywhere.
What are alternating and inverse case for?
Mostly for fun — social posts, usernames and jokes. Alternating case switches capitals letter by letter; inverse case flips each letter to the opposite of what you typed.
Can I download the converted text?
Yes — the Download button saves it as a plain .txt file, and the Copy button puts it on your clipboard.
