All 3 case styles

Capitals and small letters 3

  • lowercase Every capital becomes a small letter. Digits, punctuation, spaces and accents stay as they are: CAFÉ ÉCLAIR becomes café éclair. The pronoun I and every name go small with the rest.
  • Sentence case Small letters with a capital put back at the start of each sentence and on I, the days and most months. March and May stay small, because both are ordinary words too, and so does a name that is not listed under Protected words: IT IS MAY. I MET ANNA IN PARIS ON FRIDAY. becomes It is may. I met anna in paris on Friday.
  • UPPERCASE Every small letter becomes a capital. Text that is already in capitals is left as it is, and the row then says No change, as it does for the sample.

How it works

This uppercase to lowercase converter makes every capital in your text a small letter as you type. It opens on a line written with Caps Lock on. The UPPERCASE row goes the other way.

All caps to lowercase, and the capitals you still need

lowercase takes every capital off, the I and the first letter of each sentence included: sorry, i left caps lock on. Sentence case is the row for text that must read normally again: Sorry, I left caps lock on. The box arrives on Monday.

Lowercase to uppercase, and what does not come back

UPPERCASE capitalizes all letters and keeps accents: café becomes CAFÉ. One letter does not survive the round trip. The German ß becomes SS, so straße turns into STRASSE and returns from lowercase as strasse. Greek fares better: ΟΔΥΣΣΕΥΣ comes back as οδυσσευς, with its final sigma in place.

Questions and answers

How do I uncapitalize text?

Paste it into the box. The lowercase card removes the capital letters: everything is decapitalized, and one press copies it. If each sentence should keep its first capital, copy Sentence case instead.

How do I make text all caps?

Type or paste it and copy the UPPERCASE row. It turns the small letters to caps and leaves the capitals already there alone.

What are uppercase and lowercase letters?

Uppercase letters are the capital letters (A, B, C) and lowercase letters are the small letters (a, b, c). Printers kept the type for capitals in the upper of two cases and the small letters in the lower, which is where both names come from.

Can it convert all caps to mixed case?

Yes. Sentence case is the mixed case row: small letters, with capitals only where a sentence needs them. To capitalize every word of a title instead, use the Start Case or Title Case row of the case converter.
