Title Case capitalizes the first letter of each major word in a sentence. Small words like 'a', 'an', 'the', 'and', 'or', 'but', 'in', 'on', 'at', 'to', 'for' are kept lowercase unless they appear at the start of the sentence.

What is sentence case?

Sentence case capitalizes only the first letter of the first word in a sentence (and proper nouns), while keeping all other letters lowercase. It mirrors standard English sentence formatting.

❓ Frequently Asked Questions

What is a text case converter? +

A text case converter is an online tool that transforms your written text into different letter case formats — such as UPPERCASE, lowercase, Title Case, sentence case, camelCase, snake_case, and more. It saves time compared to manually retyping or reformatting text.

What is the difference between Title Case and Sentence case? +

Title Case capitalizes the first letter of every major word (nouns, verbs, adjectives), while keeping minor words (a, an, the, and, or, but, in, on, at, to, for) lowercase — unless they begin the title. Sentence case only capitalizes the very first word of a sentence, leaving everything else lowercase, just like standard English writing.

What is camelCase and who uses it? +

camelCase is a naming convention where multiple words are joined without spaces, with the first word entirely lowercase and each subsequent word starting with a capital letter (e.g., "myVariableName"). It is widely used by software developers for naming variables and functions in languages like JavaScript, Java, and Swift.

Is this case converter tool free and private? +

Yes! The ToolCentrix text case converter is 100% free with no registration required. All text processing happens entirely in your browser using JavaScript — your text is never uploaded to any server, so your content remains completely private and secure.
