Why Every Writing Workflow Needs a Title Case Converter
Capitalisation rules vary by style guide, platform, and use case — and getting them wrong signals a lack of editorial polish to readers and editors alike.

Every output updates live as you type and can be copied with one click.

Use Cases
Apply AP or Chicago Style to Blog and Article Titles
Publications and content teams follow specific style guides for headline capitalisation. AP Style is standard for journalism and press releases; Chicago Manual of Style is common in book publishing and long-form editorial. Paste your working title, select the correct guide, and get a properly capitalised headline instantly — no style guide reference needed.
Convert Titles to camelCase or PascalCase for Development
Developers frequently need to convert human-readable labels into code-safe variable names. PascalCase is standard for React component names, TypeScript interfaces, and class names in object-oriented languages. camelCase is used for JavaScript variables, function names, and JSON keys. Paste a description, and copy the programmer-case output directly into your IDE.
Generate snake_case and kebab-case for File Names and URLs
Linux file systems are case-sensitive, and web servers on Linux treat MyImage.png and myimage.png as different files. Using consistent snake_case for Python files and kebab-case for web-facing assets prevents path-related bugs. The kebab-case output is also directly usable as a URL slug — copy it and paste it into your CMS.
Standardise Text Case in Content Migrations
When migrating content between platforms, heading styles often become inconsistent — some pages use Title Case, others use Sentence case or ALL CAPS. Run each heading through this tool to standardise capitalisation across your content library before import, saving hours of manual correction work.
Format Email Subject Lines and UI Copy
Email subject lines and UI button labels typically use Sentence case rather than Title Case, as research shows Sentence case reads more naturally in inbox and interface contexts. Use this tool to quickly convert a Title Case draft into Sentence case without retyping — particularly useful when working across both editorial and product copy in the same session. For a fresh set of article title ideas before you decide on capitalisation style, the headline generator offers 20 scored options per topic.
FAQ's
AP style capitalises words of four or more letters and always capitalises the first and last word. Chicago style is more nuanced — it lowercases coordinating conjunctions (and, but, or), articles (a, an, the), and most prepositions regardless of length, but capitalises prepositions used adverbially or adjectivally. Use Chicago for books and long-form editorial; AP for news and press releases.
MLA style is similar to Chicago but treats all prepositions as lowercase regardless of length, including "between", "through", and "without". APA style capitalises major words of four or more letters and also capitalises the first word after a colon or em-dash. Both are common in academic writing.
Yes. Numbers are preserved in place. Words adjacent to numbers are treated as separate tokens — "top 10 tips" becomes "top10Tips" in camelCase and "Top10Tips" in PascalCase. The exact output depends on how numbers appear in the original input.
Sentence case capitalises only the first letter of the entire string and the first letter after sentence-ending punctuation (. ! ?). All other words remain lowercase. It mirrors how a normal sentence is written and is recommended for UI copy, email subject lines, and social media captions.
Google treats hyphens as word separators in URLs, so "how-to-cook-pasta" is read as four separate words, which helps with keyword matching. Underscores are not treated as word separators, making snake_case URLs less effective for SEO. Google's John Mueller has explicitly confirmed the hyphen preference for URL slugs.
dot.case is primarily used for configuration file keys (e.g., log.level, server.port) and package name conventions in some programming ecosystems. It is rarely used for URLs or headings. The dot.case output is useful for developers working with configuration-driven applications or property-path notation.
No. All conversions happen entirely in your browser using JavaScript. No text is ever sent to a server or stored anywhere. The tool works fully offline once the page has loaded.
