FAQ
- What's the difference between camelCase, PascalCase, snake_case, and kebab-case?
- camelCase joins words with the first word lowercase and each following word capitalized (helloWorld) — common in JavaScript variables. PascalCase capitalizes every word (HelloWorld) — common for class names. snake_case joins words with underscores (hello_world) — common in Python and databases. kebab-case joins words with hyphens (hello-world) — common in URL slugs and CSS classes.
- Which words does Title Case leave lowercase?
- Short function words are left lowercase mid-sentence: a, an, and, as, at, but, by, for, if, in, nor, of, on, or, so, the, to, up, yet, via, with. The first and last words are always capitalized.
- Does it handle emoji and accented characters?
- Yes. Emoji are left untouched, and accented letters (é, ñ, ü) are converted correctly using the browser's Unicode case-mapping rules.
- Is my text uploaded?
- No — conversion happens entirely in your browser.
