No. Conversion happens in your browser. Your text is not sent, saved or logged, and it disappears when you clear it or close the page.

Each line is treated as a separate title. The first and last word are capitalised, and short words such as a, an, and, as, at, but, by, for, in, nor, of, on, or, per, the, to, via and vs stay lowercase in the middle, except after a colon. It is a simple English rule, not a full style guide, so check the result.

Both modes lowercase the text first, so acronyms, names, brands, URLs and abbreviations such as NASA or iPhone may need manual fixing afterwards.

Capitalize Words uppercases the first letter of every word, including short words like “of” and “the”. Title Case keeps those short words lowercase in the middle of a line.

They run before the case change, in this order: trim line edges, collapse repeated spaces, remove empty lines, then remove line breaks. Removing line breaks also removes paragraph structure, joining everything with single spaces.
