Case Converter

In Title Case, “the quick brown fox” becomes “The Quick Brown Fox” — every word capitalised, the rest lowered.

How it works

Typed a paragraph with Caps Lock on? Need a headline in Title Case, a shout lowered to a sentence, or a meme in alternating case? Choose the style and the converted text appears in the panel, ready to copy — the original stays untouched in the box.

Title Case here follows the simple every-word rule used by most headline tools; style guides that keep small words (a, the, of) lowered differ on those words, and the method note owns the difference rather than hiding it.

The method

UPPER/lower map every letter. Title Case lowercases the text, then capitalises the first letter of each word (after spaces and opening brackets/quotes). Sentence case capitalises the first letter of the text and after each ., ! or ?. Capitalized Words capitalises the first character of every whitespace-separated word. Alternating flips case by character position; Inverse flips each letter's existing case.

Check important dates twice. Every result here is worked out from the values you enter and the calendar, clock and counting conventions described on the page. Date and time answers can depend on time zones and daylight-saving rules, and counting tools follow the definitions printed with them. For deadlines, filings, payroll or anything with money attached, confirm the figure against an authoritative source.

Frequently asked questions

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

Nearly nothing in output: Title Case also lowercases the rest of each word first and capitalises after brackets and quotes; Capitalize Every Word works strictly word by word. On ordinary text they agree.

Does it fix text typed with Caps Lock on?

Yes — run it through lowercase or Sentence case and the shouting is gone, with sentence starts re-capitalised in Sentence mode.

Is my text stored?

No. Conversion happens in your browser; nothing is uploaded.
