Title case sounds simple, capitalise the important words, and then the questions begin. Is it a Tale of Two Cities or A Tale Of Two Cities? Does with get a capital in a subtitle? What about the second word of a hyphenated compound, or the word after a colon? The answers depend on the style guide, and the major guides disagree. AP lowercases short prepositions of three letters or fewer, Chicago lowercases all prepositions, APA capitalises words of four letters or more, and MLA lowercases articles, short prepositions and coordinating conjunctions.

Title case converter
Paste one or more titles, one per line, and convert them to title case in AP, Chicago, APA or MLA style, or to sentence case, upper case or lower case.
The title case converter needs JavaScript, and it works in your browser without sending anything that you enter to a server.
Overview
What the title case converter does and why it helps
The converter applies those rules for you. Paste your titles, one per line, choose AP, Chicago, APA or MLA, and the tool returns each title in that style, always capitalising the first word, the last word and the first word after a colon or dash. It also keeps all-caps words such as ISBN and USA as they are, and it can produce sentence case, which capitalises only the first word and proper names you keep, as well as plain upper and lower case. A copy button makes it easy to move the result into your document.
For authors, the most common uses are book and chapter titles, series names, subtitles, blog headings and the metadata fields of retail platforms. Consistency matters more than any one style, so pick a style, apply it everywhere and record the choice in your style sheet. If you publish in a particular market or follow a publisher's guide, use the style that guide specifies.
The title case converter turns a heading into correct title case, capitalising major words and keeping small words such as of, and, the in lower case. This is a free title case converter, built for authors who want a clear answer without buying software. You can use the title case converter online in any modern browser, with nothing to install. We built it as a title case converter for authors, with book-specific defaults. If you publish independently, treat it as a title case converter for self-published books of any length.
Authors use this title case converter tool for chapter titles, book titles and subtitles. If you prefer working in a spreadsheet, a title case converter in Excel works, and developers sometimes write a title case converter in Python or a title case converter Python script, or even build a title case converter freecodecamp style as a coding exercise. For a single book, a ready-made page is faster. Those who follow the Chicago manual can use a title case converter Chicago option, and a title case converter extension is handy while you browse. It also helps to know the difference in a sentence case vs title case converter choice: sentence case capitalises only the first word, while a to title case converter capitalises the major words.
How to use it
How to use the title case converter, step by step
Enter your titles
Type or paste one or more titles, one per line. The tool converts every line at once, which saves time when you are preparing a list of chapters, a catalogue or a set of headings.
Choose a style
Select AP, Chicago, APA or MLA, or choose sentence case, upper case or lower case. Each title style has its own rules for small words, so your choice changes the result.
Read the result
The converted titles appear below. Compare them with the original and note where the rules changed a word, such as a preposition or a conjunction that should stay lowercase.
Check small words and acronyms
Articles, conjunctions and short prepositions stay lowercase unless they begin or end a title. Acronyms such as ISBN stay in capitals, and the tool keeps them.
Check the word after a colon
Most styles capitalise the first word after a colon. The tool applies the rule, but read the result in case your title needs an exception.
Copy and use
Copy the result into your manuscript, store listing or contents. Keep the same style throughout the book and the series. If a value looks wrong, change it and read the result again; the title case converter never stores or uploads what you enter.
How the title case converter works
One list of titles, converted by the rules of the style you pick
Paste your titles, one per line, choose a style and the tool converts each line. For title case, it capitalises the first and last words and the word after a colon, keeps articles, conjunctions and short prepositions in lower case according to the style, and leaves all-capital acronyms alone.
The styles differ in small ways. AP keeps short prepositions of three letters or fewer in lower case, Chicago keeps prepositions of any length in lower case, APA capitalises words of four letters or more and MLA follows rules close to Chicago. The tool applies the main rule of each, and you can check proper names by eye.
It also converts to sentence case, upper case, lower case and capitalise-every-word. Everything runs in your browser, so a private manuscript's headings are never uploaded, and each result has a copy button so that you can paste it straight back into your document.
- Four title case styles plus sentence, upper and lower case
- One title per line, many at once
- Copy each line or all of them
Method
How the title case converter works out its answer
Words that stay lowercase
In title case, short articles such as a, an and the, coordinating conjunctions such as and, but, for, nor, or, so and yet and prepositions of the right length stay lowercase unless they come first, last or after a colon.
The four styles
AP lowercases prepositions of three letters or fewer, Chicago lowercases all prepositions, APA capitalises every word of four letters or more, and MLA lowercases articles, coordinating conjunctions and prepositions. The tool applies the list for the style you choose.
First, last and after a colon
The first word and the last word are always capitalised, and so is the first word of a subtitle after a colon or an em dash, as the major guides require.
Acronyms and sentence case
Words that are already in capitals, such as NASA or ISBN, are left alone in title case. Sentence case lowercases everything, then capitalises the start of each sentence and the pronoun I.
Tips
Getting the most from the title case converter
Pick a style at the start
Choose AP, Chicago, APA or MLA when you begin and keep to it for chapter titles, headings and metadata. The title case converter is free and instant, so it is worth running again whenever your book changes.
Convert a series together
Run all of your series titles at once so that they share a style and a pattern in every store. Make the title case converter a routine step on every project, so that results stay consistent from book to book.
Read the colon rule
Check how your chosen style treats the first word after a colon, since it is the commonest place for a title to look wrong.

Client reviews
What authors say about our manuscript style edit service
Verified reviews from authors who asked a specialist to handle the manuscript style edit after using the title case converter.
My KDP file was rejected with a technical error message I could not understand. Book Formatting Experts diagnosed the problem immediately — a bleed issue on three pages — and corrected it the same day. Approved first time.
My YA novel needed to reach both English-language and Japanese readers. The multi-region distribution setup was handled correctly across all required platforms. International sales have exceeded my expectations.
As a first-time author, the technical side of self-publishing was genuinely daunting. The consultation covered every decision — platform choice, pricing strategy, metadata, and distribution. I launched with genuine confidence.
Getting historical fiction placed in the right categories on Amazon and IngramSpark required strategic metadata. The team understood the genre classification and the book reached the right readers from the first week.
Navigating IngramSpark's requirements for the first time felt overwhelming. The upload assistance handled everything — metadata, pricing setup, distribution channels. My children's book reached bookstores within two weeks.
Good support throughout the KDP upload process. The metadata setup and category selection were explained clearly. One pricing setting needed adjustment after initial setup but it was corrected quickly.
The publishing readiness review identified four issues in my manuscript that would have caused rejection. Each was clearly explained and quickly resolved. My book launched without any technical complications.
Good publishing support overall. The KDP metadata setup was thorough. One category selection needed updating after initial launch but it was corrected promptly. The book is performing well in its target categories.
My cookbook needed to be set up across multiple platforms simultaneously. The publishing support team handled every submission — KDP, IngramSpark, and Apple Books — with different requirements for each. Flawlessly executed.
The formatting error fix service saved my launch. My original formatter had made margin errors causing repeated rejection. Book Formatting Experts identified and fixed every issue within 48 hours. My launch was back on schedule.
The dark, atmospheric design matches the tone of my crime novels without feeling clichéd. New readers understand the genre and mood of my work immediately from the homepage. My ebook sales from website referrals increased by 60%.
Literary fiction covers require a completely different approach from genre fiction. The design is elegant, restrained, and communicates the literary quality of the book. I am genuinely proud to show it to readers.
The romantic atmosphere of the cover design is exactly right for my readership. The colour temperature, the typography, and the visual composition all signal the genre clearly without being generic.
My fantasy EPUB had complex nested structures with chapter epigraphs and world-building inserts. The EPUB handles every level cleanly and reads beautifully on Kindle and Apple Books.
The interior design reflects the purpose of the book — accessible, warm, and inviting for daily reading. The scripture placement and reflection boxes are formatted consistently throughout. I am genuinely proud of how it looks.
Good formatting work on my early reader book. The large font and generous spacing were applied correctly. One illustration needed repositioning in revisions but it was fixed quickly. Happy with the result.
My memoir had photographs on almost every other page alongside the text. The image placement, captions, and page flow all look natural and professional. The print proof was exactly what I hoped for.
My business book had 14 chapters, 38 tables, and 22 figures. Everything was formatted cleanly and consistently. The specialist flagged two source document errors I had not noticed. Thorough and professional.

What is the difference between AP and Chicago title case?
AP lowercases prepositions of three letters or fewer, while Chicago lowercases all prepositions. Both capitalise the first and last word.
Which title case style should I use for a book?
Many publishers use Chicago, and many news outlets use AP. Use the style your publisher or platform prefers and apply it everywhere.

Should the word after a colon be capitalised?
Yes, in the major styles the first word of a subtitle is capitalised.
