When you actually need this

- Normalising names and emails imported with random capitalisation.
- Preparing title-cased headings from lowercase drafts.
- Fixing a paragraph typed with caps lock on before it ships anywhere.
The edge cases of "simple" casing
Naive title case capitalises every word, but English style guides lowercase short articles and prepositions mid-title — "The Lord of the Rings", not "Of The" — so treat automated title case as a first pass on headlines. Proper nouns with internal caps (McDonald, iPhone, PhD) do not survive round trips through lower and back; check them after converting. Case rules are also language-dependent — German capitalises nouns, Turkish distinguishes dotted and dotless i — so review non-English output rather than trusting it blind.

FAQ
How does Case Converter count characters with spaces and emoji?
It reports both a count with spaces and one without, so you can match whichever rule your form uses. Emoji and other characters outside the basic range are counted as a single visible character rather than as the two code units JavaScript stores internally.
Does Case Converter work for languages other than English?
Yes. Korean, Japanese, Chinese, Hindi, Arabic and accented European text are all handled correctly. Word counting splits on whitespace, so for Chinese and Japanese the character count is the more meaningful figure.
Is my text saved anywhere?
No. Everything runs in the page itself and nothing is transmitted or stored — you can paste a draft, a contract or private notes without it leaving your device.
