What is Online Title Case Converter?
Online Title Case Converter is a free browser-based tool that rewrites any headline you paste into correct title case according to the style guide you choose, then lets you copy the result with one click. It takes seconds, and there is no account, download or email address involved.
We built it for the exact moment when a headline is already written and only the capitalisation is wrong. A UK blogger pasting a draft out of WordPress, a sub-editor checking a standfirst, a student formatting a title page — they all want the same thing: the right capitals, fast.
Everything happens on the tool page itself. Nothing is uploaded to a queue, and there is no sign-up screen sitting between you and the converted title. It sits alongside the other free online tools on OnlineFree.app and, like them, does one job properly.
How do you use the converter, step by step?
Paste your headline into the text area. The input is trimmed automatically, and anything longer than 20,000 characters triggers a friendly "too long" notice rather than failing silently. Conversion is live, debounced by 120 milliseconds, so the output panel refreshes as you type without flickering on every keystroke.
Next, choose a style from the selector. It defaults to British. Below that sit four toggles: keep small words lowercase, capitalise after a colon, preserve acronyms, and capitalise hyphenated words. Leave all four switched on unless your house style says otherwise — they match the defaults most UK publications use.
Then read the result panel. The converted title is the largest element on the page, with a Copy button beside it and a "Copied" confirmation once it reaches your clipboard. Underneath, a stat line reports what changed — for example "9 words capitalised · 4 small words kept lowercase · 2 acronyms preserved" — and a collapsed list names the exact rules applied, so you can audit the conversion instead of trusting it blindly.
Choosing the right style guide for your title
As of 2026 the style selector offers six options: British, Chicago, AP, MLA, sentence case, and simple. British follows Guardian-style UK book practice, Chicago and AP are the US book and news standards, MLA is what most humanities essays expect, sentence case capitalises only the first word plus proper nouns, and simple capitalises every single word.
For most UK web writing, British is the right default, and it is what the tool loads with. Writing for a US outlet? Switch to AP. A US book manuscript? Chicago. Academic work in the humanities usually wants MLA, while UK government and public-sector copy generally uses sentence case, which the GOV.UK style guide sets out in detail.
The styles diverge far more on small words and after colons than anywhere else, so the choice matters most for long headlines with prepositions and subtitles. On a three-word headline, British, Chicago and AP will usually produce identical output.
Small words, acronyms and hyphens explained
With "keep small words lowercase" switched on, the converter holds back 23 short words: a, an, and, as, at, but, by, for, from, in, into, nor, of, on, onto, or, over, the, to, up, via, with, yet. Capitalise after colon is a separate toggle, and it applies to a colon, an em dash and a question mark in the middle of a title — so with it on, "SEO: the basics" keeps its capital on "The".
Acronym preservation is the feature most people do not realise they need. Any token already in capitals and at least two letters long — UK, AI, NASA, SEO — keeps its casing, and so does anything containing a digit, such as COVID-19. Without that switch, aggressive capitalisation would turn "UK" into "Uk" and quietly ruin a headline.
Hyphenated and slashed words get both sides capitalised when the relevant toggle is on: "State-of-the-Art" rather than "State-of-the-art". If you prefer the lighter newspaper look, switch it off — both approaches are defensible, and the change summary shows exactly what the tool did so you can make that call deliberately.
Common mistakes and honest limits
This is a casing tool, not a grammar or style checker. It does not know which words are brand names, surnames with internal capitals such as McCartney, or proper nouns from languages with different rules, so check those by hand afterwards. Nor can it tell you whether your title should be title case at all — plenty of editorial styles want sentence case everywhere, and only your own style guide can settle that.
Paste plain text rather than HTML or markdown markup. The converter treats everything in the box as words, so tags and syntax characters are handled as ordinary characters and a stray <h1> will happily appear in your output.
Finally, treat the result as a strong first draft rather than a guarantee. Style guides disagree with one another about small words, capitals after colons and hyphen practice, and publishers layer house rules on top. If a title really matters — a print headline, a journal article, a client's homepage — compare it against your style guide before it ships. The Online Title Case Converter lists the rules it applied precisely so that check takes seconds.
Frequently asked questions
Is Online Title Case Converter free, and does it need an account?
Yes. Online Title Case Converter is free to use and requires no account, download or email address. You paste a headline, pick a style and copy the result, all on the tool page. The conversion runs in your browser, and the only practical limit is the 20,000-character cap on the input box.
Which style should I choose for a UK headline?
British is the default and the best starting point for UK blogs, magazines and web copy, because it follows Guardian-style practice. Switch to AP or Chicago for US publications, MLA for humanities essays, and sentence case for UK government or public-sector writing. Short headlines often come out identically across all the title-case styles.
Does the converter capitalise small words like "of" and "the"?
No, not by default. With keep small words lowercase switched on, Online Title Case Converter holds back 23 short words — including of, the, and, to and with — and leaves them lowercase inside the title. Turn the toggle off, or choose the simple style, if you want every word capitalised.
Will acronyms such as UK, AI and NASA stay in capitals?
Yes. Acronym preservation is on by default, so any token already in capitals and at least two letters long keeps its casing — UK, AI, NASA, SEO. Tokens containing digits, such as COVID-19, are left alone too, so they are not mangled into title case.
What can Online Title Case Converter not do?
It fixes capitalisation only. It cannot identify brand names, surnames with internal capitals, or the correct title style for your publication, and it treats pasted HTML or markdown as ordinary text. Always compare important headlines against your own style guide before publishing, especially for print or client work.
