How it works
Changes the capitalisation of a text in one click: all uppercase, all lowercase, title case (each word capitalised), or sentence case (only the first letter of each sentence).
Example
"hello WORLD. how are you" → Title: "Hello World. How Are You" · Sentence: "Hello world. How are you".
Frequently asked questions
Does it handle accents and special letters?
Yes, it works with Unicode, so accents, umlauts, and letters like ñ convert properly.
Does title case capitalise articles and prepositions?
Yes, every word gets an initial capital. For strict editorial styles, review small words by hand.
