Frequently asked questions
What is the difference between title case and sentence case?
Title case capitalises the first letter of every word. Sentence case capitalises only the first letter of each sentence, as in ordinary text.
Does it work with accented letters?
Yes. Letters such as “é”, “ñ” or “ü” are converted to their matching capital or small letter and keep their accent.
Can I undo a change?
You can apply another case to the same text as many times as you like. If you turn everything into uppercase or lowercase, the original capitalisation is lost.
What each case does
The typical situation is a text typed with Caps Lock on, or a list copied from a spreadsheet or a PDF that arrives in all caps. Instead of typing it again, you paste it and choose how you want it.
Title case capitalises the first letter of every word, which is useful for names or for headlines. Sentence case leaves a capital only at the start of each sentence, which is how ordinary text is written.

Accents, names and opening punctuation
Accented letters are converted like any other: “é” becomes “É”, “ñ” becomes “Ñ” and “ü” becomes “Ü”, and back again. That matters for names and for words borrowed from other languages, such as “café” or “naïve”.
Opening punctuation (quotation marks, brackets, or the Spanish “¿” and “¡”) does not count as the first letter: in sentence case, “(hello there)” becomes “(Hello there)”. Proper nouns cannot be detected automatically, and neither can the small words that style guides leave in lowercase in titles, so it is worth checking them after converting.
