Do accented letters work?

Yes. "café" becomes "CAFÉ" and "CAFÉ" becomes "café". Letters from other Latin alphabets are converted too.

Can I convert a very large text?

Yes. The conversion is instant even with several pages of text.

Is the text sent to a server?

No. Everything happens in your browser. When you close the page the text is gone, unless you save it to a note.

How do I change only part of the text?

Paste only the part you want to convert, copy the result and replace it in the original text.

The text is processed in your browser and is not sent anywhere.

How to use it

Paste or type your text in the first box.
Under "Convert to", pick the format. The result shows up instantly in the second box.
Click "Copy result" and paste it where you need it, or use "Save to a note" to keep it.

What each option does

UPPERCASE: every letter in capitals. Useful for acronyms, notices and headings.
lowercase: every letter in small letters. The way out for anyone who left Caps Lock on.
Capitalize Every Word: each word starts with a capital, including "of", "the" and "and". Good for names of people and places, lists and labels.
Title Case: like the previous one, but keeps short articles, conjunctions and prepositions (a, an, the, and, but, or, for, of, in, on, to…) in lowercase, except for the first and last word. It is the most common format for book, film and article titles.
Sentence case: everything in lowercase, with a capital at the start of the text, after a period, exclamation or question mark, and at the start of each line.

When to use each format

Different style guides disagree on how much to capitalize in a headline, so pick one and stay consistent. Many news sites and blogs now prefer sentence case, which reads more naturally, while books, films and formal documents often use Title Case.

Avoid long blocks of text in UPPERCASE: they are harder to read and, in messages, tend to sound like shouting.

Watch out for acronyms and proper names

The conversion does not know what an acronym or a proper name is. When you convert to lowercase or sentence case, acronyms like NASA and FBI and names like Maria and London also become lowercase. Review the result before using it.
