Case Converter & Text Cleaner

Capitalizes major words while keeping minor prepositions in lowercase.

Sentence case capitalises only the first word of each sentence plus proper nouns, exactly as you would write ordinary prose. Title case capitalises most words in a heading, typically excluding articles ('a', 'the'), short conjunctions ('and', 'but'), and short prepositions ('of', 'in') unless they appear first. Most publications now prefer sentence case for headings because it reads more naturally.

They are conventions for joining words without spaces. camelCase starts lowercase and capitalises each subsequent word (userName). PascalCase capitalises every word including the first (UserName). snake_case joins words with underscores in lowercase (user_name). kebab-case uses hyphens (user-name). Each language community has settled on different defaults, which is why converting between them comes up so often.

Yes. Conversion uses the browser's Unicode-aware case mapping, so accented Latin, Greek, and Cyrillic all convert correctly. Some language-specific rules — Turkish dotted and dotless i, for instance — follow the default Unicode mapping rather than locale-specific behaviour.

No. Conversion runs entirely in your browser and nothing is transmitted or stored.

Not within the tool once you convert — the original capitalisation is not retained. Keep a copy of the source text if you may need to return to it.
