Title Case Converter

Capitalize titles and headings correctly

Titles are where capitalization mistakes are most visible: blog post headlines, report and chapter titles, slide headings, email subject lines, and product names. Paste a title — or a whole list of them, one per line — and each one is capitalized using common English title-case conventions, so you do not have to remember which small words stay lowercase.

How to convert text to title case

1. Type or paste one title per line, or choose Upload Document to open a .txt, .md, .docx, or .pdf file.
2. The Title Case version appears immediately below.
3. Check any names, phrasal verbs, or style-guide requirements, then Copy Result or Replace Input with Result (Undo Replace restores the original).

The capitalization rules used

• Main words — nouns, verbs, adjectives, adverbs, and pronouns — are capitalized.
• Articles (a, an, the), coordinating conjunctions (and, but, or, nor, for, so, yet), and prepositions of three letters or fewer (such as of, in, on, to, at, by) stay lowercase.
• The first and last word of each title are always capitalized, and so is the first word after a colon or dash.
• Each part of a hyphenated word is capitalized (Well-Known), and acronyms and brand names such as NASA and iPhone are kept as typed.

Style guides differ

These are common English title-case conventions, not the exact rules of any one style guide. AP, APA, Chicago, and MLA disagree on some words — most often longer prepositions such as “with” or “through” — so for formal or published work, compare the result with the style you are required to follow.

Your text stays on your device

• Text is converted by JavaScript running in your browser.
• Your text is never uploaded to Looty Tools or any other server.
• Uploaded documents are opened and read in your browser; the file itself is never sent to Looty Tools.
• Nothing is stored — refreshing or closing the page clears both boxes.

Limitations

• Uploads accept .txt and .md files up to 5 MB, Word .docx files up to 15 MB, and PDFs up to 25 MB and 50 pages. Older .doc files are not supported, scanned or image-only PDFs have no text to convert, and formatting such as bold or italics is not kept.
• Short words are judged by spelling, not grammar, so a phrasal-verb particle stays lowercase (“Log in”, “Set up”) where many style guides would capitalize it.
• A line typed entirely in capitals is treated as ordinary words, so acronyms inside it are not kept. Names such as “O’Brien” lose the capital after the apostrophe.
• The rules are for English titles; other languages have their own capitalization conventions.

Title Case Converter FAQ

Which words stay lowercase?

Articles (a, an, the), coordinating conjunctions (and, but, or, nor, for, so, yet), and prepositions of three letters or fewer (such as of, in, on, to, at, by) — unless they are the first or last word of the title or follow a colon or dash.

Does this follow AP, APA, Chicago, or MLA style?

Not exactly. It applies common English title-case conventions. The major style guides disagree on some words — for example, whether a four-letter preposition like “with” is capitalized — so check the result against the style you are required to use.

What happens to acronyms and brand names?

Words that are already all capitals (NASA) or use inner capitals (iPhone, McDonald’s) are kept as typed. If a whole line is in capitals, it is treated as ordinary words and converted.

Can I convert several titles at once?

Yes. Put each title on its own line. Every line is capitalized as a separate title, so its first and last words are always capitalized.

Why is the “in” in “Log in” not capitalized?

The tool treats short words by their spelling, so it cannot tell when “in”, “on”, or “up” is part of a phrasal verb. Many style guides would write “Log In” or “Set Up” — fix those by hand after converting.

How is this different from the Case Converter?

The Case Converter lets you switch between six case styles. This tool does one job — capitalizing titles and headings — and shows the result immediately without choosing a style.

Can I upload a Word document or PDF instead of pasting?

Yes. Upload Document accepts .txt, .md, Word .docx, and text-based .pdf files, or you can drop a file onto the text box. The file is read in your browser — it is not sent to Looty Tools — and its text replaces whatever is in the box. Scanned PDFs without a text layer and older .doc files are not supported.

Is my text kept private?

Yes. Titles are converted in your browser and never uploaded to Looty Tools or saved. Refreshing the page clears them.
