Your text is converted on your own device and never sent to us.

Retyping a paragraph because it arrived in capitals is a waste of a morning. Paste it above, choose a case, and copy the result. The conversion happens on your own device, so there is no upload, no character limit and no queue, however much text you give it.

Title Case follows the convention shared by the Chicago and AP style guides: the important words are capitalized, and articles, conjunctions and short prepositions are left alone unless they open or close the line. Hyphenated compounds are handled properly, so mother-in-law becomes Mother-in-Law rather than Mother-In-Law.

What each case does

Title Case

The Quick Brown Fox Jumps Over the Lazy Dog

Capitalizes the important words and leaves the small ones alone, the way a headline or a book title is written. Articles, conjunctions and short prepositions stay lowercase unless they open or close the line.

Sentence case

The quick brown fox jumps over the lazy dog.

Capitalizes the first word of every sentence and lowercases the rest. The usual way to rescue a paragraph that arrived in capitals.

UPPER CASE

THE QUICK BROWN FOX JUMPS OVER THE LAZY DOG

Makes every letter a capital. Useful for headings, short labels and acronyms, though whole paragraphs in capitals are noticeably harder to read.

lower case

the quick brown fox jumps over the lazy dog

Makes every letter small. The usual first step before applying another case, and what you want for tags, slugs and email addresses.

When to use which case

Headlines and titles

Blog post titles, article headlines, book and chapter titles, and most marketing headings use Title Case. Check your publication style guide first: some house styles prefer sentence case for headlines, and consistency matters more than which one you pick.

Text that arrived shouting

Pasted something written entirely in capitals? Sentence case puts it back to normal in one click, rather than retyping it. This is the single most common reason people reach for a case converter.

Spreadsheets and imported data

Names, addresses and product lists exported from another system often arrive in inconsistent case. Convert a column at a time and paste it back.

Code, tags and URLs

Slugs, tags, hashtags and email addresses are conventionally lowercase. Converting first avoids duplicate entries that differ only by capitalization.

Accessibility

Screen readers can spell out words written in capitals letter by letter, and long stretches of capitals are slower for everyone to read. If you have inherited a page full of them, sentence case is a genuine accessibility improvement.

Subject lines and social posts

Email subject lines and social captions are usually sentence case. Capitals read as shouting and, in email, correlate with spam filtering.

Case converter questions

How do I change text to title case?

Paste your text into the box above and press Title Case. Every important word is capitalized and the small ones, such as a, an, the, and, of and to, are left lowercase unless they begin or end the line. The converted text replaces what you pasted, and Undo puts it back.

How do I change capitals back to normal text?

Paste the text and press Sentence case. It lowercases everything, then capitalizes the first word of each sentence, which is what you want for a paragraph that arrived entirely in capitals. Use lower case instead if you want no capitals at all.

Which words stay lowercase in title case?

Articles (a, an, the), coordinating conjunctions (and, but, or, nor, for, yet, so) and short prepositions (at, by, in, of, on, to, up, via) stay lowercase, following the convention shared by the Chicago and AP style guides. Longer prepositions such as between and through are capitalized. The first and last word of a line is always capitalized, as is the first word after a colon.

Does it handle hyphenated words?

Yes. A compound such as mother-in-law becomes Mother-in-Law: the parts are capitalized, but a small word inside the compound stays lowercase, which is the standard convention.

Is my text uploaded anywhere?

No. The conversion runs entirely in your browser using local JavaScript. Your text is never sent to our server, never written to a database, and never passed to any third party or AI service. You can disconnect from the internet and the converter still works, which is the simplest proof of that.

Is there a limit on how much text I can convert?

No. Because the work happens on your own device rather than on a server, there is no upload limit, no character cap and no queue. Very large documents are limited only by your browser.

Can I undo a conversion?

Yes. Press Undo, or the usual keyboard shortcut, and your text returns exactly as it was. Nothing is saved or sent while you work, so nothing is lost by experimenting.

Does it work on a phone?

Yes. The converter is designed for small screens as well as desktops, and needs no app, no account and no payment.

What is the difference between title case and sentence case?

Title case capitalizes most words in a line, so it reads as a heading. Sentence case capitalizes only the first word of each sentence, so it reads as ordinary prose. Titles and headlines usually take title case; body text, email subject lines and social captions usually take sentence case.

Once the case is right, the free word counter and text analyzer gives you words, characters, sentences, reading time and the phrases you repeat, with the same sixteen counting rules you can switch on and off.
