What does a text case converter do?
A case converter changes the capitalisation of text without retyping it. It’s perfect when you accidentally type with Caps Lock on, need a headline in Title Case, want to fix an ALL-CAPS email, or must format variable names for code.

Title Case rules
Our Title Case follows the conventions used by major style guides: capitalise the first and last word and all major words (nouns, verbs, adjectives, adverbs, pronouns), and keep short articles, conjunctions and prepositions — a, an, the, and, but, or, of, in, on, to, for, with — in lowercase unless they start the title or follow a colon.
Tips for writers and SEOs
- Use Title Case or Sentence case consistently for all headings on your site.
- Convert headlines to kebab-case to create clean, SEO-friendly URL slugs.
- Avoid ALL CAPS in emails and ads — it reads as shouting and can trigger spam filters.
Frequently asked questions
