Title Case Capitalizes The First Letter Of Every Major Word, following standard book and article title conventions.

What is sentence case?

Sentence case capitalizes only the first word of each sentence — like normal prose writing.

Does it change numbers or punctuation?

No. Only alphabetic letters are affected. Numbers, punctuation, and special characters remain unchanged.

Can I convert a whole document at once?

Yes. Paste any amount of text and all conversions happen instantly with no size limit.

Why convert case online instead of retyping?

Programmers need camelCase/snake_case for variable names, writers need Title Case for headlines, and editors need Sentence case for body copy — doing it by hand is slow and error-prone for long strings.

When is kebab-case or snake_case useful?

kebab-case is the URL and CSS standard (hello-world). snake_case is common in Python and database columns (hello_world). Use these when you need identifiers that match existing coding conventions.
