About this tool
Accidentally typed with caps lock on, or need a headline in title case? Paste your text and pick a case. Title Case capitalizes major words and keeps short words (a, and, of, the, to…) lowercase except at the start, following common AP/Chicago-style rules. Sentence case capitalizes the first letter of each sentence.
Programmer cases (camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE) convert each line separately, which is handy for renaming variables or CSS classes.
FAQ
What is the difference between Title Case and Capitalized Case?
Capitalized Case capitalizes every word. Title Case leaves minor words like “and”, “of” and “the” in lowercase unless they start the title.
Does it work with accented and non-English letters?
Yes, it uses Unicode-aware case mapping, so é → É, ß, Cyrillic and Greek all work.
Is there a limit on text length?
No practical limit — it runs locally, so even very long documents convert instantly.
