What you can type into Case Converter

UPPERCASE and lowercase
Every letter is switched. Punctuation, digits, spaces and line breaks are untouched.
Title Case
Each word is capitalised except short articles, conjunctions and prepositions such as a, an, the, and, or, of and in — which stay lowercase unless they start or end the title.
Sentence case
Everything is lowercased, then the first letter of the text, of each new line and of each sentence after . ! or ? is capitalised. Names are not re-capitalised, so check them afterwards.
camelCase, snake_case, kebab-case
The text is split on spaces and punctuation and rejoined with no separator, underscores or hyphens. Punctuation is dropped, digits are kept, and line breaks disappear because these formats describe a single identifier.

How the results behave

All formats at once
One paste produces every variant simultaneously, each with its own copy button — there is no mode to switch.
Non-destructive
Your original input stays in the box, so you can copy one format and then another.

Tips

  • kebab-case is the safe choice for URLs, file names and CSS classes; snake_case suits Python and SQL; camelCase suits JavaScript variables.
  • Sentence case is the modern default for buttons and UI labels because it reads faster than Title Case.

Common mistakes

  • Running a paragraph through camelCase and expecting the punctuation to survive — identifier formats strip it by design.
  • Trusting Sentence case with proper nouns: "paris" will not be restored to "Paris".

About the case converter

Developers renaming variables, files and CSS classes, editors fixing headings pasted in capitals, and anyone tidying text that arrived in the wrong case.

Case conventions carry meaning in code: camelCase for JavaScript variables, snake_case in Python and SQL, kebab-case for URLs, CSS classes and file names. Converting by hand is slow and error-prone.

For prose, Title Case suits headings while Sentence case is the modern default for UI labels and buttons because it reads faster.

Accuracy and limitations

  • Title Case follows one common style guide's word list. Publications differ, so check against your own house style.
  • Conversion is text-based and does not know which words are names, acronyms or brand spellings.

Frequently asked questions

Which words stay lowercase in Title Case?

Short articles, conjunctions and prepositions such as a, an, the, and, or, of and in — unless they start or end the title.

Does converting change my punctuation?

Upper, lower, title and sentence case keep punctuation. camelCase, snake_case and kebab-case strip it, since those formats are for identifiers.
