🧐 Frequently Asked Questions

What is Title Case?

Title Case capitalizes the first letter of every major word (e.g., "The Quick Brown Fox"). Use this style for headlines, book titles, and formal branding.

Can I undo a conversion?

Conversion is a one-way process. Once you convert text to lowercase, the original capitalization is lost. We recommend keeping a backup of your original draft if you need to revert.

📚 Trivia

CamelCase is named for the "humps" created by capital letters in the middle of a word. While it appeared in chemical formulas decades earlier, it became a software engineering staple in the 1970s and remains the standard for languages like Java and JavaScript.
