Smart Title Case Converter – With Headline Scorer and Programmer Cases
Convert text to APA, Chicago, MLA, AP title case. Score headlines, protect custom terms, use programmer cases (camelCase, snake_case), toggle original, and auto‑save. All private, no server needed.
Your Headlines Deserve to Shine – Here's How
We built this Title Case Converter because we've been in your shoes. Staring at a blinking cursor, wondering whether that little preposition should be uppercase or lowercase, checking three style guides at once. It's not just about rules – it's about making sure your work looks as professional as you are.
With a single text box that grows as you type, you can paste an entire draft, click a button, and watch your headlines transform. No account, no uploads, no tracking. All the heavy lifting happens inside your browser.
The Headline Score on the stats bar is something we wish someone had given us years ago. It counts power words, emotional triggers, and ideal length – giving you instant feedback on whether your title is ready to grab attention or needs a little more muscle. If you see a green badge, your headline is doing its job.
For the developers, the Programmer Cases row converts your plain English into camelCase, PascalCase, snake_case, kebab‑case, or CONSTANT_CASE in one click. If you've ever had to manually rewrite variable names from a product spec, you'll wonder how you ever lived without this.
Beyond the Buttons: Real Title Case Rules That Matter
Most free converters apply a simplistic "capitalize every word" rule. That might work for email subject lines, but it's wrong for academic writing, journalism, and publishing. Here's a quick look at the four major style guides and what they actually expect:
- APA Style (American Psychological Association) – Capitalize the first word of the title and subtitle, all nouns, pronouns, verbs, adjectives, adverbs, and subordinating conjunctions (like "because", "although"). Lowercase articles (a, an, the), coordinating conjunctions (and, but, or), and all prepositions – yes, even four‑letter ones like "with" or "from". The only exception is the first or last word of the title.
- Chicago Style (Chicago Manual of Style) – Very similar to APA, but Chicago goes a step further and lowercases *all* prepositions, regardless of length. Words like "between" or "through" stay lowercase unless they're the first or last word.
- MLA Style (Modern Language Association) – Capitalize the first and last words and all principal words. Articles, coordinating conjunctions, and prepositions are lowercased. MLA doesn't care about preposition length; "under", "above", "along" – all lowercase.
- AP Style (Associated Press) – A different beast. Capitalize all words with four or more letters, plus the first and last words. Short conjunctions and prepositions (three letters or fewer) are lowercase. This gives a very clean, news‑ready look that works beautifully for press releases and blog posts.
Don't worry about memorizing all this. Click a button, and the tool applies the exact rules for you.
Common Title Case Mistakes (We Made Them So You Don't Have To)
- Capitalizing short prepositions in APA. "With" should stay lowercase in APA unless it's the first word. Many writers capitalize it anyway because it feels important. Trust the style guide, not your gut.
- Forgetting that the last word is always capitalized. Even a tiny word like "up" gets a capital letter if it's the last word. Our tool never misses this.
- Using sentence case for headlines. Sentence case (only the first word capitalized) has its place in emails, but for article titles and blog posts, title case increases readability and click‑through rates.
- Ignoring brand names. You never want "iPhone" to become "Iphone". That's why we added the Custom Terms feature – add your brand words once, and they'll stay protected across all conversions.

Stories from People Just Like You
Meera, Ph.D. Candidate, New Delhi
"My advisor pointed out inconsistent capitalization in my chapter titles. I pasted the entire table of contents here, picked APA, and everything was fixed. It took maybe 30 seconds. I wish I'd known about this in my first year."
Alex, Full‑Stack Developer, Berlin
"Our project manager sent a feature list written as normal sentences. I needed them as camelCase variable names. I pasted the whole list, clicked camelCase, and had my variables. This tool literally saved me an hour of boring find‑and‑replace."
Sophie, Lifestyle Blogger, Cape Town
"I always used to capitalize every word because I didn't know the rules. Now I use AP style, and my post titles look so much cleaner. The score badge helps me test different versions – I won't publish anything under 60!"
Raj, Digital News Editor, Mumbai
"Our CMS doesn't auto‑format headlines, so I'd manually retype them. Now I keep this page open in a pinned tab, paste, click AP, copy, and I'm done. It's become part of our newsroom workflow."
Why We Chose Privacy Over Convenience
Most online text tools send your data to a server, process it, and (sometimes) store it. We don't. The entire converter runs in your browser using JavaScript. You can unplug your internet after loading the page and it'll still work flawlessly.
This means your draft headlines, confidential product names, and even sensitive academic paper titles stay on your device. We never see them, and they never leave your control. That's a promise.
