The four cases
UPPERCASE makes every letter capital, lowercase makes them all small, Title Case capitalises the first letter of each word (great for headings), and Sentence case capitalises only the first letter of each sentence. One click converts your whole text.
When it saves time
Fixing a line typed with Caps Lock on, cleaning up a heading pasted in all caps, formatting a list consistently, or tidying text copied from a PDF — all are a single tap here instead of retyping. Use the Copy button to grab the result for anywhere else.
Frequently asked questions
How do I undo a conversion?
Convert again to another case, or use your keyboard's undo (Ctrl/Cmd + Z) inside the text box.
Does Title Case capitalise small words?
It capitalises the first letter of every word, including short ones like "and" and "of".
Is my text private?
Yes — conversions happen entirely in your browser and nothing is uploaded.
