Title Case Converter

This tool takes a line or block of text and rewrites it so each major word starts with a capital letter, while a fixed set of short connecting words stays lowercase in the middle of the phrase. It is built for the moment you have a headline, heading, or name that was typed in a hurry and needs to read as a deliberate title rather than a sentence.

The realistic fits are narrow and concrete. Writers and editors use it to normalize article headlines and section headings before publishing. Web and marketing teams clean up page titles, button labels, navigation items, and product or feature names so they look consistent across a site. In office and admin work it tidies document headings, slide titles, spreadsheet column labels, and list entries pulled from a messy export.

Because it runs entirely in your browser with nothing uploaded and nothing kept after the tab closes, it is also reasonable for text you would rather not paste into an unknown server, such as internal project names or unreleased headings. It is a formatting helper, not a copy editor, so treat it as a fast first pass.

The flow is direct: paste your text into the input box (it shows live word and line counts), press Run or use Cmd/Ctrl+Enter, and the result appears in the output box. From there you can Copy it to the clipboard or Download it as a plain UTF-8 text file named formatos-title-case-converter.txt. A reset control restores the sample text so you can start over.

Under the hood the tool first lowercases everything, then capitalizes the first letter of every word. It then forces a specific list of small words back to lowercase, but only when they sit in the middle of the text: a, an, and, as, at, but, by, for, in, nor, of, on, or, per, the, to, and vs. The very first and very last word of the whole input are always left capitalized.

What it deliberately does not do is just as important. There is no choice of style guide (AP, Chicago, MLA), no custom small-word list, no per-line title handling, and no file upload or drag-and-drop. It processes whatever text sits in the box as a single block of plain text.

The biggest pitfall is that the tool lowercases your text before recapitalizing, so any intentional casing is lost. Acronyms become title-cased words (NASA turns into Nasa, PDF into Pdf), and brand or product spellings with internal capitals are flattened (iPhone becomes Iphone, McDonald's becomes Mcdonald's, eBay becomes Ebay). Proper nouns are only ever given a single leading capital.

The small-word handling is mechanical and English-only. Because the first and last word of the entire input are always capitalized, a small word at the very end of a multi-line block may be capitalized when you expected it lowercase, and small words not on the list (such as from, with, into, over) are always capitalized. Words like vs are lowercased mid-phrase, which may not match every style you follow.

Other quirks: hyphenated and apostrophe-joined words are capitalized at each word boundary, Roman numerals and unit abbreviations get normal title casing, and the tool has no awareness of sentences or proper-noun context. Long inputs are fine since it is plain text, but everything is treated as one undifferentiated block.

Scan the output for the predictable failure points first: restore any acronyms, brand names, and intentional internal capitals by hand (Nasa back to NASA, Iphone back to iPhone). Then check the connecting words against the style you intend, since words off the built-in list stay capitalized and the first and last words are always capitalized regardless of what they are.

Also confirm the input was a genuine title and not a sentence or paragraph, because the tool will capitalize most words in a sentence and produce something that reads oddly. If you converted several lines at once, remember the first-and-last-word rule applies to the whole block, not per line, so review line breaks individually.

For anything official, legal, financial, or externally published, verify the result manually against the relevant style guide or the canonical spelling of each name. This tool gives you a consistent starting point; the final judgment on proper nouns and house style is yours.
