Frequently Asked Questions

1 What's the difference between Title Case and Capitalized Case?
Title Case capitalizes every major word (typically words with 4+ letters), while Capitalized Case capitalizes the first letter of every single word, regardless of length. For example: "The Quick Brown Fox" (Title Case) vs "The Quick Brown Fox" (Capitalized Case — note shorter words remain capitalized).
2 Does the tool preserve original formatting like line breaks?
Yes. All whitespace, line breaks, and punctuation are preserved exactly as in your original text. Only the letter cases are modified, so your formatting remains intact for easy copying and pasting.
3 What does "tOGGLE cASE" do exactly?
tOGGLE cASE inverts the case of every letter in your text. All uppercase letters become lowercase, and all lowercase letters become uppercase. For example: "Hello World" becomes "hELLO wORLD". It's perfect for fixing accidentally caps-locked text.
4 Is my text stored or accessible by third parties?
Never. All text processing occurs entirely within your browser's JavaScript engine. No data is ever transmitted to any server, stored in cookies, or accessible by us or any third party. Your content stays private and secure on your device.
5 Can I convert text from other languages like French or Chinese?
Yes! The tool fully supports Unicode, so it works with any script that has a case distinction — Latin, Greek, Cyrillic, Armenian, and more. For scripts without case (like Chinese, Japanese, or Arabic), the text is preserved as-is.
