📰 Title Case That Matches Real Editorial Style Guides

Title Case rules aren’t universal. APA and Chicago treat short words like of, to, and, with, and by differently. This converter applies the selected guide automatically while always capitalizing the first and last words. Choose your style once and keep headings consistent across blogs, docs, and product pages.

🧑‍💻 Developer-Focused Formats

Consistent naming is essential in codebases. Instantly convert between:

• camelCase — JavaScript variables and functions.
• snake_case — Python and configuration files.
• kebab-case — URLs, CSS classes, filenames.
• dot.case — Config keys and file patterns.

🧹 Cleaning Pasted Text

Text from PDFs, email, or chat often includes tabs, double spaces, or hard breaks. Clean Text removes redundant whitespace; Remove Line Breaks flattens content into a web-friendly paragraph. Clean first, then convert for the best result.

📈 Word Count & Full Text Statistics

Editors and SEO teams work with limits. The counter shows words and characters; the stats panel adds sentences, paragraphs, average word length, longest word length, and reading time — reliable guardrails for titles, meta descriptions, and paragraphs.
