Frequently asked questions
What is the difference between Title Case and Capitalize Each Word?
Title Case capitalises the first letter of each word and lowercases the rest, so “HELLO world” becomes “Hello World”. Capitalize Each Word only raises the first letter of each word and leaves the other letters as you typed them.
How does Sentence case work?
The whole text is lowercased first, then the first letter of every sentence is capitalised — a sentence being a chunk ending in a full stop, question mark or exclamation mark. The very first letter is capitalised even if there is no punctuation yet.
Is my text uploaded or stored?
No. Conversion happens entirely in your browser as you type, and nothing is sent to a server. Closing the page erases the text.
Does it work with languages other than English?
Yes, for any language that uses upper and lower case letters — the browser's built-in case conversion handles accented characters too. Languages without capital letters, such as Chinese or Arabic, are left unchanged.
