About the case converter

Which case should I use?

UPPER CASE suits headlines and warnings but is hard to read in long passages. Title Case is standard for headings, book titles and blog posts. Sentence case capitalizes only the first word after sentence-ending punctuation, which is how most modern websites write prose.

What about camelCase, PascalCase, snake_case and kebab-case?

These programmer conventions remove spaces entirely: camelCase starts lowercase and capitalizes each following word (often used for JavaScript variables), PascalCase capitalizes every word (class names), snake_case joins words with underscores (Python, SQL), and kebab-case joins words with hyphens (URLs, CSS classes, file names). Words are extracted from your text automatically, so punctuation is stripped.

Does it handle accented letters?

Yes — case conversion and word extraction use Unicode-aware rules, so letters like é, ñ and ü convert correctly.

Is anything sent to a server?

No. The conversion happens in JavaScript inside your browser, and the page works offline once loaded.
