How this tool works
Each line is treated as a separate title. Words are lowercased first, then their first letter is capitalized except for supported connecting words such as a, an, the, and, of, and to inside the line. The first and last word are always capitalized. Punctuation and spacing are retained, and line endings are normalized to LF. This is a general rule, not an implementation of a named editorial style guide.
Input and output stay in the current page. Refreshing or closing the page clears them. For very large inputs, use Run to start processing; a task that takes too long is stopped so you can change the input.
Frequently asked questions
Which words stay lowercase in the middle of a title?
The current list is a, an, the, and, but, or, nor, for, so, yet, at, by, in, of, on, to, up, as, per, via, and vs. These words are still capitalized when they are the first or last word on a line.
Does this preserve acronyms or follow APA, MLA, or Chicago rules?
No. Words are lowercased before title capitalization, so NASA becomes Nasa. The tool uses its own fixed connecting-word list. Review acronyms, proper names, and the requirements of your chosen style guide.
Can I capitalize a list of titles in one operation?
Yes. Put one title on each line. The first-word and last-word rules restart on every line.
