  • AP Style Logic Engine: A robust JavaScript ruleset that capitalizes principal words while keeping articles, short conjunctions, and short prepositions lowercase, unless they start or end the headline.

  • Character & Word Count: Real-time statistics display to track headline length.

  • Main Tool Area:
    • A large, auto-focusing textarea for user input.
    • A secondary output area that is read-only, highlighting the converted text.
    • A button control panel below the input area featuring style toggles and action buttons.
  • Responsive Design:
    • Mobile: Single column flow, textarea expands to fill width.
    • Desktop: Sidebar or grid view for statistics (character/word count) while maintaining a central focus for the text input.

4. Design & Aesthetics

  • Color Palette: High-vibrancy light mode.
    • Background: #FFFFFF (White)

5. Technical Directives

  • Single File: All HTML, CSS, and JS must reside in one .html file. CSS in <style> block, JS in <script> block.
  • No Persistence: Do not use localStorage, sessionStorage, or cookies. Maintain state solely through variable manipulation in the JavaScript runtime.
  • No Popups: Do not use alert(), confirm(), or prompt(). All notifications (e.g., 'Copied to clipboard') must be displayed as custom, non-intrusive UI elements (toasts or status labels).
  • Accessibility: Use semantic HTML5 tags (<main>, <section>, <textarea>, <button>). Ensure high color contrast ratios for accessibility.
  • Performance: No heavy frameworks. Pure Vanilla JavaScript only.

Frequently Asked Questions

Everything you need to know about using this application.

What is AP Style title case?

The Associated Press (AP) style for title case requires capitalizing the first and last words of titles and all principal words. This includes nouns, pronouns, verbs, adjectives, and adverbs. Conversely, you should lowercase articles (a, an, the), coordinating conjunctions (and, but, for, or, nor), and prepositions of three or fewer letters unless they are the first or last word of the title.

Why use an online title case converter?

Manually applying capitalization rules to every word in a headline is time-consuming and prone to human error, especially with complex phrases. An online converter automates this process instantly. By using this tool, you ensure professional consistency across your articles, blog posts, or social media content, adhering strictly to the recognized journalistic standard without needing to memorize every specific guideline.

Does this tool support other capitalization styles?

While this tool is specifically optimized for AP Style headline capitalization, it functions as a comprehensive text case manipulator. You can easily toggle between Sentence case, UPPERCASE, lowercase, and Title Case to suit different publication requirements. This makes it a versatile utility for writers who need to quickly reformat text for various platforms, whether they are working in marketing, SEO content creation, or academic writing.

Is this tool secure to use?

Yes, this application runs entirely within your local browser environment. We do not store, track, or transmit your text data to any server, ensuring your content remains private and confidential. Because the app operates in a single-file, client-side architecture without the use of cookies or local storage, no data persists once you refresh or close the page. You can safely paste sensitive headlines without risk of data leaks.
