What is the difference between Title Case and Capitalize Each Word?

Capitalize Each Word puts a capital at the start of every word. Title Case follows headline style: short articles, conjunctions and prepositions such as a, and, of, in and with stay lowercase unless they are the first or last word or follow a colon. Use Title Case for headlines and blog titles.

How does sentence case work?

Sentence case makes everything lowercase and then capitalises the first letter of each sentence. A new sentence starts after a full stop, question mark, exclamation mark or ellipsis followed by a space, and at the start of every line. The word I is always capitalised.

What does Keep acronyms and brand names do?

With it on, words written in capitals (NASA, SEO, B2B) and words with a capital in the middle (iPhone, YouTube, URLs) are left exactly as you typed them in Title Case, Sentence case and Capitalize Each Word. If your whole text is in capitals, the option is ignored so the text still converts.

What are camelCase, snake_case and kebab-case used for?

They are naming styles used in code and URLs. camelCase and PascalCase are common for variables and class names, snake_case and CONSTANT_CASE in Python and for constants, kebab-case in URLs and CSS class names, and dot.case in config keys. Each line of your text is converted separately, so you can convert a list of names at once.

Does the converter work with accented letters and other languages?

Yes. Upper, lower and the capitalising cases use your browser's Unicode rules, so letters such as é, ñ, ß and Cyrillic or Greek letters convert correctly. Languages without upper and lower case, such as Chinese or Arabic, are left as they are.

Is there a length limit?

No fixed limit. The tool has been built to handle text of a megabyte or more. With very long text, results update a moment after you stop typing so the page stays responsive.

Is my text stored anywhere?

No. The conversion runs in your browser and nothing you type is uploaded or saved.

Which case to use, and when

Text that arrives in the wrong case is common: a heading typed with Caps Lock on, a product list exported in capitals, or a variable name that needs to match a different naming style. Retyping it is slow and easy to get wrong. This tool converts the whole text in one click.

Title Case for headlines, blog titles, YouTube titles and email subject lines.
Sentence case for captions, buttons, menus and most body copy. It reads more naturally than Title Case and is the default in many style guides.
UPPERCASE for short labels only. Long passages in capitals are harder to read and come across as shouting in comments and DMs.
camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE and dot.case for code, file names, URL slugs and config keys.

How the title case rules work

Words of four letters or fewer that are articles, conjunctions or prepositions (a, an, the, and, but, or, for, of, in, on, at, to, with, from, into, over and similar) stay lowercase in the middle of a title. The first and last word, and any word after a colon or dash, are always capitalised. Style guides such as AP and Chicago differ on a few words, so read your headline once before you publish it.

Converting code identifiers

The programming cases split words at spaces, punctuation and existing capital letters, so “XMLHttpRequest”, “xml_http_request” and “XML http request” all become “xmlHttpRequest” in camelCase. Apostrophes are dropped, and every line is converted on its own.
