Small but smart details
Title Case follows editorial convention: minor words (a, an, the, of, for…) stay lowercase unless they start the text. Sentence case capitalizes the first letter of every sentence. The result box shows a live word and character count, and the copy button grabs the output instantly.
Typical uses: fixing text written with Caps Lock on, preparing variable names from plain phrases, cleaning up spreadsheet exports, and formatting headlines.
Frequently asked questions
What is the difference between Title Case and Sentence case?
Title Case capitalizes most words ("The Quick Brown Fox"), the standard for headlines and book titles. Sentence case capitalizes only the first word and proper nouns ("The quick brown fox"), the style most news sites and product UIs use.
When do I use camelCase vs snake_case?
camelCase and PascalCase dominate JavaScript, Java and C#. snake_case is the convention in Python, Ruby and SQL. Kebab-case is standard for URLs, CSS classes and file names. Use the button matching your language’s style guide.
Does the converter change my original text?
No. Your input stays untouched in the top box; the transformed copy appears in the result box so you can try multiple cases from the same text without re-pasting.
Is there a length limit?
No practical one — everything runs in your browser, so it handles long documents as fast as you can paste them.
