Title case rules
Most style guides capitalise the first and last word and all “important” words (nouns, verbs, adjectives, adverbs). Short articles, conjunctions and prepositions such as a, an, the, and, but, or, for, of, in, to stay lowercase unless they start the title. The converter follows this rule. Is “and” capitalised in a title? Normally not, unless it is the first word.

Frequently asked questions
How do I change uppercase to lowercase?
Paste the text and click “lowercase”. Every letter becomes small. Use “Sentence case” if you want capitals at the start of sentences.
Is “and” capitalised in a title?
No. In title case, short words like and, or, but, of, the and to stay lowercase unless they are the first word.
Does it work with accented letters?
Yes. Letters such as é, ñ, ü and ç are converted correctly.
What is camelCase?
Words are joined without spaces and every word after the first starts with a capital: myVariableName. It is common in programming.
Can I convert text in Word or Google Docs?
Word has Shift+F3; Google Docs has Format → Text → Capitalisation. This tool adds title, sentence and programming cases they do not have.
