Manually retyping text to change case is tedious and error‑prone. Our tool gives you six different case transformations in one click: sentence case (capitalises first letter of each sentence), UPPER CASE, lower case, Title Case (capitalises major words), tOGGLE cASE (reverses case), and Capitalize Words (capitalises every word). All processing is done locally, so your data remains private. Use it for writing, programming, social media, or any text editing task.
Capitalises the first letter of each sentence. All other letters are lower case.
It reverses the case of every character: uppercase becomes lowercase and vice versa.
