Case Converter
Paste your text and turn it into UPPER CASE, lower case, Title Case or Sentence case with one click. Turkish i/İ and ı/I are handled correctly too.
This tool runs entirely in your browser; what you enter is never sent to our servers.
How to use it
- Type or paste your text.
- Pick a conversion: UPPER, lower, Title or Sentence case.
- Copy the result; for Turkish text, switch the language rule to “Türkçe”.
Why a language rule?
Turkish has a dotted and a dotless i: i becomes İ in upper case, and ı becomes I. With the English rule, “i” becomes “I” as you'd expect; with the Turkish rule, “istanbul” becomes “İSTANBUL”. Title case capitalises the first letter of every word; sentence case capitalises only the start of each sentence (after a full stop, exclamation or question mark, and at each new line).
