Frequently Asked Questions

What is Title Case exactly?
Title Case capitalizes the first letter of each word. Hayırte: strict AP/Chicago style keeps short articles and prepositions (a, the, of) lowercase — this tool capitalizes every word for simplicity. For headline style, review the output manually.
What is camelCase vs PascalCase?
camelCase starts with a lowercase letter and capitalizes each subsequent word: firstName. PascalCase capitalizes the first letter too: FirstName. JavaScript variables typically use camelCase; class names use PascalCase.
When should I use snake_case vs kebab-case?
Use snake_case for Python variables, database column names, and environment variable file names. Use kebab-case for URLs, HTML attributes, CSS class names, and CLI flags.
Does the converter handle special characters?
Yes. Accented letters (é, ñ, ü), emojis, numbers, and punctuation are preserved. Only letter case and separators are changed. For camelCase / kebab-case conversions, spaces and underscores are treated as word boundaries.
Is my text private?
Completely. The entire conversion runs in your browser using JavaScript string methods. Hayırthing is sent to any server, nothing is logged.
Can I convert very long text?
Yes — the tool handles text up to several megabytes without lag. Conversion is O(n) complexity, meaning a 10 MB document converts in under a second on modern devices.
