Frequently asked questions

Quick answers about this tool.

What is the difference between Title Case and Capitalize Each Word?

Capitalize Each Word capitalizes the first letter of every single word. Title Case follows headline rules instead: small joining words like “the”, “a”, “of” and “and” stay lowercase in the middle of a headline — “The Lord of the Rings”, not “The Lord Of The Rings”.

How does Sentence case work?

Everything is lowercased first, then the first letter of the text and the first letter after every full stop, question mark or exclamation mark is capitalized — the way normal sentences look.

How does alternating case work?

Letters take turns: the first letter is lowercase, the next uppercase, and so on (aLtErNaTiNg). Spaces and punctuation don’t use up a turn.

Is there a size limit?

No practical one — the conversion happens instantly in your browser, so even long documents are fine.

Is my text private?
