Frequently asked questions
What is the difference between title case and capitalising each word? +
Title case follows editorial rules: articles, short prepositions and conjunctions (a, an, the, of, in, and, or…) stay lowercase unless they start or end the title. Capitalising each word puts a capital on every word regardless.
How do I change case in Word or Google Docs? +
In Word, select the text and press Shift+F3 to cycle through lowercase, UPPERCASE and Capitalize Each Word. Google Docs has Format → Text → Capitalization. For sentence case or programming cases, use this tool and paste the result.
Does sentence case fix proper nouns? +
No. It capitalises the first letter after each full stop, question mark or exclamation mark and lowers everything else, so names inside a sentence will be lowered. Check them after converting.
Is my text sent anywhere? +
No. The conversion runs in your browser. Nothing is uploaded.
