Supported cases
UPPERCASE and lowercase change every letter. Title Case capitalizes the first letter of each major word and keeps minor words (a, an, the, of…) lowercase. Sentence case capitalizes the first letter of each sentence. camelCase, PascalCase, snake_case, and kebab-case are formats used in programming and for URL slugs.
Title Case follows a common style-guide convention where short connecting words stay lowercase unless they begin the title. You can always copy and tweak the result.
Examples
| Example | Input | Result |
|---|---|---|
| Title Case | the lord of the rings | The Lord of the Rings |
| snake_case | Hello World Example | hello_world_example |
| UPPERCASE | shout this | SHOUT THIS |
Frequently asked questions
What is the difference between Title Case and Sentence case?
Title Case capitalizes the major words in a heading ("How to Write Well"). Sentence case capitalizes only the first word and proper nouns ("How to write well").
Why do small words stay lowercase in Title Case?
Most style guides keep short articles, conjunctions, and prepositions (a, an, the, of, and) lowercase unless they are the first or last word.
