Case Converter
Convert text between UPPER, lower, Title Case, sentence case, camelCase and kebab-case.
The Case Converter transforms text into six different cases from one box: UPPERCASE, lowercase, Title Case, Sentence case, camelCase and kebab-case. It is the formatting Swiss-army knife for headlines, code identifiers, filenames, form fields and style-guide compliance.
Each case has a job: UPPERCASE for emphasis and acronyms, Title Case for headlines and book titles, Sentence case for most web and email copy, camelCase and kebab-case for code, URLs and file names. Title Case here follows the common headline convention that leaves small words like 'and' and 'the' lowercase unless they start the title.
The output updates as you type or switch modes, and one click copies the result. Everything runs locally in your browser — paste sensitive drafts freely.

Frequently asked questions
What is the difference between Title Case and Sentence case?
Title Case capitalizes the first letter of most words, keeping short conjunctions and prepositions ('and', 'of', 'the') lowercase unless they start the title — the headline style used by most publishers. Sentence case capitalizes only the first word of each sentence.
When should I use camelCase versus kebab-case?
camelCase ('myVariableName') is standard in JavaScript and Java. kebab-case ('my-variable-name') is used in URLs, CSS classes and file names. Neither contains spaces, which is why both appear in the converter's code-oriented outputs.
Is uppercase text harder to read?
Yes — all-caps text slows reading because words lose their shape, which is why UPPERCASE is best used sparingly for short emphasis. For long content, sentence case is the readability winner, with Title Case for headings.
