What this site is
TitleCaseMaker is a small suite of browser-based text utilities built around one common frustration: getting capitalization right. English style guides disagree about how titles should be capitalized, and switching between APA, Chicago, AP, MLA and AMA by hand is tedious and error-prone. Our title case converter applies the exact rule set you choose in a single click, so you can stop second-guessing whether "with" or "between" should be capitalized.
Around that core we have built a wider toolbox — a word counter, sentence case converter, uppercase-to-lowercase and lowercase-to-uppercase converters, capitalize-each-word, alternating case, reverse text, remove line breaks, and fancy Unicode text generators for social media.
Our principles
- Free and unlimited. No account, no paywall, no daily limits. Every tool is free to use as often as you like.
- Private by design. All conversion happens in your browser with JavaScript. The text you paste is never uploaded to a server — we literally cannot see it. Read more in our Privacy Policy.
- Fast and lightweight. Each tool is a single static page with no heavy frameworks, so results appear instantly as you type.
- Accurate. Our title-case engine encodes the documented small-word rules of each major style guide, including first/last word and post-colon capitalization.
Who it's for
Students formatting essay and reference titles, bloggers and content marketers polishing headlines, authors and editors preparing manuscripts, journalists writing AP-style headers, and social-media creators who want eye-catching bold or strikethrough text. If your work involves typing a heading, one of these tools probably saves you a minute.
How we keep the rules accurate
A capitalization tool is only as good as the rules behind it, so accuracy is a maintenance job, not a one-time build. Each of our five title-case modes is written against a specific, named edition of its source: the Publication Manual of the American Psychological Association, 7th edition; The Chicago Manual of Style; the current AP Stylebook; the MLA Handbook, 9th edition; and the AMA Manual of Style, 11th edition. When a guide publishes a new edition or revises its capitalization guidance — as AP does with its regular stylebook updates — we review the relevant sections and adjust our word lists and logic to match before anything else on the site changes.
The engine itself is rule-based rather than statistical: an explicit list of articles, coordinating conjunctions and prepositions (with each style's length threshold), plus the positional rules — first word, last word, and first word after a colon. That design is deliberate. It means the same input always produces the same output, and when a user reports an edge case we can trace the exact rule that fired and fix it once for everyone. Reader reports are genuinely part of the process: several of the edge cases documented in our tricky cases guide started as bug reports from the contact page.
What our rule data covers
It is just as important to be clear about scope. The converters implement each guide's headline-style capitalization rules: major and minor word classes, the preposition treatment that separates APA, AP and AMA from Chicago and MLA, hyphenated compounds, and subtitle capitalization after a colon. They also cover the general-purpose transformations around that core — sentence case, UPPERCASE, lowercase, capitalize-each-word and alternating case — plus counting tools and Unicode text generators.
What the rules cannot decide for you: whether a word is a proper noun (apple the fruit versus Apple the company), brand spellings such as iPhone or eBay, acronyms the engine has no way to recognize, and judgment calls like phrasal-verb particles, which depend on meaning rather than spelling. We would rather tell you that plainly than pretend otherwise — so the tools handle the mechanical ninety-five percent instantly, and our guides section teaches the judgment calls, from a full comparison of the five style guides to the mistakes we see most often in real titles.
