About Title Case

This tool uses the common editorial convention: every word is capitalized except short "small words" (a, an, and, as, at, but, by, for, in, of, on, or, the, to) — and the first and last words are always capitalized. Different style guides (AP, Chicago, MLA) disagree on details, so treat the output as a solid starting point.

Frequently asked questions

Is my text sent anywhere?

No — conversion happens entirely in your browser. Nothing you type leaves your device.

Why fix caps lock text here instead of retyping?

Click "Sentence case" and a WHOLE PARAGRAPH TYPED WITH CAPS LOCK ON becomes normal writing in one click, keeping sentence starts capitalized.

Does camelCase/snake_case handle punctuation?

Yes — spaces, hyphens, underscores, and punctuation between words become the separator of the chosen style, and everything else is stripped, so "Hello, World! 2.0" becomes hello_world_2_0.
