How It Works
Paste or type text, then click a case button to convert. Supports uppercase, lowercase, title case, sentence case, alternating case, and inverse case.
The conversion is instant and works on any length of text. Title case intelligently capitalizes the first letter of each word, while sentence case capitalizes only the first letter after sentence-ending punctuation.
