Questions
- Which words stay lowercase in Title Case?
- Short articles, conjunctions and prepositions such as a, an, the, and, but, or, of, in, on, to and by stay lowercase, unless they are the first or last word or follow a colon. Words with inner capitals, like iPhone or NASA, are kept as written.
- How do camelCase, snake_case and kebab-case handle my text?
- The text is split into words at spaces, punctuation, underscores, hyphens and case changes, so “Hello World”, “hello_world” and “helloWorld” all become hello_world in snake_case. Apostrophes are dropped and each line is converted separately.
- Is my text stored?
- No. The conversion runs in your browser and nothing is sent or saved.
