What is Case Converter?
Case conversion is everywhere — from cleaning up shouty all-caps emails to normalizing data for comparison. This tool offers four modes: UPPERCASE, lowercase, Sentence case (capitalizes the first letter of each sentence), and tOGGLE cASE (flips the case of every letter).
FAQ
- Does it work with non-English characters?
- Yes. Uppercase/lowercase use unicode rules that work for most scripts.
- Is my text uploaded to a server?
- No — every conversion runs entirely in your browser. Your text never leaves your device.
- What does 'Sentence case' actually do?
- It capitalizes the first letter of each sentence and lowercases the rest, so you get clean, properly formatted prose.
