Frequently Asked Questions about Text Case Converter
- What is the difference between the case styles?
- UPPERCASE makes every letter a capital. lowercase makes every letter small. Title Case capitalizes the first letter of each word (good for headings). Sentence case capitalizes only the first letter of the text, like a normal sentence.
- What is sentence case?
- Sentence case capitalizes the first letter of the text (and leaves the rest lowercase), just as you would write a normal sentence. For example, 'the report is ready' becomes 'The report is ready'.
- What is title case?
- Title case capitalizes the first letter of each word, which is the common style for headlines and titles - for example 'a tale of two cities' becomes 'A Tale Of Two Cities'. It is a simple word-by-word capitalization rather than a strict style-guide title case.
- Does converting case change my words or punctuation?
- No. Only the capitalization of letters changes. Your words, numbers, punctuation, spacing, and their order all stay exactly the same.
- Is my text sent to a server?
- No. All conversion happens in your browser with JavaScript, so nothing you paste is uploaded, logged, or stored.
