What it does

Useful when

- Prepare consistent labels and headings for a mockup.
- Start tidying a pasted paragraph before editorial review.
How to use it
- Paste text or load the example to see mixed capitalization.
- Choose one of the four case styles and convert the text.
- Review names and abbreviations, then copy or download the converted draft.
A few useful details
Which title-case style does this use?
Every Unicode letter-based word receives an uppercase first letter and a lowercase remainder, including short words such as “and” and “the”. Apostrophes inside words stay within the word. This is a simple capitalization style, not a publication-specific style guide.
Does sentence case understand abbreviations and names?
No. It lowercases the text and capitalizes the first letter at the start and after a period, exclamation mark, question mark, or line break. It does not distinguish abbreviations from sentence endings or restore proper names and acronyms.
Will the conversion preserve my formatting?
Spaces, punctuation, and line breaks are preserved. Unicode default casing is used rather than language-specific casing; some letters expand into multiple characters when uppercased. Up to 100,000 UTF-16 code units are processed in your browser.
