📖 What is a Case Converter?
A case converter is a text transformation tool that changes the capitalization of text. It's incredibly useful when you have text in the wrong case — for example, when you accidentally typed with Caps Lock on, need to convert headings to title case, or want to standardize text formatting for documents, emails, or code.
This tool supports six conversion modes: uppercase (all capitals), lowercase (all small letters), title case (capitalize each word), sentence case (capitalize first letter of each sentence), alternating case, and inverse case (swap uppercase and lowercase).
❓ Frequently Asked Questions
Title Case capitalizes the first letter of each word, like a book title. For example, "the quick brown fox" becomes "The Quick Brown Fox". It's commonly used for headings, article titles, and proper nouns.
Sentence case capitalizes only the first letter of the first word in each sentence. For example, "HELLO WORLD. HOW ARE YOU?" becomes "Hello world. How are you?" This is the standard capitalization for most writing.
Uppercase is typically used for acronyms (NASA, HTML), headings, emphasis, or constants in programming. Avoid using all caps in emails or messages — it's generally perceived as shouting.
