Who benefits from Online Title Case Converter?
Online Title Case Converter is a free, browser-based tool that reformats any headline you paste into correctly capitalised title case according to a style guide you select, then hands it back with a one-click copy button. It exists for people who already have a title written and only need the capitals fixed — no account and nothing to install.
The core audience is UK writers and editors. A blogger pastes a CMS headline that came out of a draft in lower case, picks the British preset and copies the result back. A sub-editor on deadline does the same with twelve headlines in a row. A marketer standardising a content calendar finally gets every post title following one rule set rather than whichever way each author typed it.
It is deliberately narrow. There are no keyword scores, no readability grades and no AI rewriting — Online Title Case Converter changes capitalisation, and that is the whole job. It sits alongside other single-purpose utilities on the site, from the free online tools index to things like Free Audio To Mp3 Converter Online Mp4, and it follows the same pattern: one task, done properly, in the browser.
Which title case style should you choose?
Choose the preset that matches whatever you are writing for, not the one that looks nicest in the preview. British suits UK book and editorial house style, Chicago is the default in US book publishing and many academic presses (The Chicago Manual of Style Online), AP is US news wire style, MLA is used in humanities papers, sentence case mimics modern newsroom headlines, and simple capitalises every single word.
The differences show up in the small words. With “keep small words lowercase” switched on, the tool leaves a, an, and, as, at, but, by, for, from, in, into, nor, of, on, onto, or, over, the, to, up, via, with and yet in lower case — unless one of them lands at the start or end of the title, where normal title-case convention capitalises it regardless of the list.
One caution for UK writers: the Guardian and Observer style guide is published online (Guardian and Observer style guide), and that outlet's own headlines are set in sentence case rather than the book-style title case the British preset produces. If you are writing to a specific house style, check the guide first, pick the closest preset, then hand-fix whatever is left.
How do the toggle settings change a headline?
Every toggle answers a decision a real editor has to make, and the defaults are sensible for general UK work. Paste “the rise of AI in UK newsrooms” with everything left on default and you get “The Rise of AI in UK Newsrooms” — three words newly capitalised, two small words kept lowercase (of, in) and two acronyms preserved (AI, UK).
“Preserve acronyms” only protects tokens that were already all caps with two or more letters, or that contain a digit. So UK, NASA and B2B survive untouched, while a lower-case “ai” you typed by hand becomes “Ai”. “Capitalise after colon” applies to a colon, an em dash and a question mark, so “why we rebuilt: a postmortem” becomes “Why We Rebuilt: A Postmortem”.
“Capitalise hyphenated” works on both sides of a hyphen or slash. If you prefer the more conservative look that keeps small words inside compounds lowercase — State-of-the-Art rather than State-Of-The-Art — switch it off. Turning off “keep small words lowercase” is the quickest route to the blunt every-word-capitalised result that some CMS templates still expect.
What the change summary tells you
Beneath the result the tool prints a small stat line, something like “9 words capitalised · 4 small words kept lowercase · 2 acronyms preserved”. It is a fast way to catch a setting you left switched on by accident, especially on a shared machine where someone else may have changed the preset.
The collapsible rules panel lists exactly which rules fired for that conversion. That matters more than it sounds, because title case is a set of conventions rather than a single law, and two style guides can genuinely disagree about the same headline. If you are checking a colleague's work, open the panel and you can see whether the difference is the tool's doing or theirs.
Treat the output as a draft, not a verdict. For anything that goes public — a client headline, a journal title, a page title in a CMS — read the finished line out loud and confirm the capitalisation of proper nouns and small words yourself before publishing.
Common mistakes and honest limits
The most common mistake is pasting a whole paragraph. Every line is treated as a title, so a block of body copy comes back with nearly every word capitalised and reads like shouting. Convert headings and titles; leave paragraphs alone, or switch to sentence case if you truly need bulk text touched.
The second is trusting acronyms you typed in lower case. There is no dictionary behind the converter, so “nasa”, “bbc” and “seo” will not be recognised as acronyms — paste them in capitals first if you want them preserved.
Third, sentence-case mode cannot repair proper nouns, because nothing tells it that London or Tesco deserve capitals. There is also a hard input cap of 20,000 characters per paste, with live conversion as you type, so very long lists of headlines need converting in batches.
None of this is a guarantee of publication-ready copy. House styles vary between publications and even between desks at the same publication, so use the tool to get 95% of the way there and keep a style guide open for the rest.
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, sign-up or installation. You paste a headline, choose a style preset and copy the result with one click. As with any web tool, avoid pasting confidential or client-sensitive text unless you have checked how the service handles input.
Does Online Title Case Converter keep UK and AI capitalised?
It preserves tokens that are already all caps with two or more letters, or that contain a digit, so UK, AI, NASA and B2B pass through unchanged. A lower-case “ai” typed by hand becomes “Ai”, because the tool has no acronym dictionary. Paste acronyms in capitals if you want them left alone.
Which title case style is best for a UK blog post?
For most UK blog and editorial work, start with the British preset, which follows UK book-style title case and keeps small words such as of, the and and in lower case. If you write for a specific publication, check its published style guide first, because some UK news outlets set headlines in sentence case instead.
Can I convert a whole article's worth of headings at once?
You can paste up to 20,000 characters in a single go, and the tool converts as you type. Each line is treated as a separate title, so it suits a list of headings or a content calendar. Avoid pasting paragraphs, because title case applied to body text capitalises almost every word.
What is the difference between title case and sentence case?
Title case capitalises the major words in a heading and usually leaves small words such as of, and and the in lower case. Sentence case capitalises only the first word plus any proper nouns and acronyms. Online Title Case Converter offers both, alongside Chicago, AP, MLA and a simple all-words-capitalised option.
