About the Case Converter

The Case Converter instantly changes the capitalisation of any text. Paste your content, then pick UPPERCASE, lowercase, Title Case, Sentence case, Capitalize Each Word, aLtErNaTiNg or InVeRsE case.

It is ideal for fixing headings, cleaning up all-caps text, formatting titles and preparing captions. Your text stays private in your browser.

For example, “the lord of the rings” becomes “The Lord of the Rings” in Title Case — the small words “of” and “the” stay lowercase because they are not the first or last word.

Frequently Asked Questions

What is the difference between Title Case and Capitalize Each Word?

Capitalize Each Word capitalises every word. Title Case follows style rules and keeps small words like “a”, “of” and “the” lowercase unless they start or end the title.

Will it change my original text order?

No. Only the letter casing changes — the words, punctuation and order stay exactly the same.

Does it support camelCase or snake_case?

Not currently. The converter handles human-readable cases (UPPERCASE, lowercase, Title, Sentence, Capitalize Each Word, aLtErNaTiNg and InVeRsE). It does not output programmer formats like camelCase, snake_case or kebab-case.

Each click changes the text in place — can I undo it?

Converting rewrites the text box, so the next case you pick works on that new result. Reversible steps like UPPERCASE then lowercase are fine, but a one-way step such as Sentence case discards the original capitalisation — paste your source again if you need a clean start.
