Case Converter

Convert text to UPPERCASE, lowercase, Title Case, camelCase, snake_case and more with one click.

How the Case Converter works

Paste your text and click any of the conversion buttons. The result appears instantly and can be copied with one click. Title Case capitalises each major word. Sentence case capitalises only the first word of each sentence. camelCase and snake_case strip spaces and format text for code use. kebab-case uses hyphens, popular in URLs and CSS class names.

Why the Case Converter is Useful

Changing text case manually is one of those tasks that sounds trivial but becomes genuinely annoying at scale. Rewriting a list of database column names from Title Case to snake_case, converting headings to UPPERCASE, or reformatting variable names one by one adds up fast. This tool handles all common case formats instantly — paste your text and convert with one click, no manual editing required.

Tips & Best Practices

  • For blog or article headings, Title Case looks more professional than Sentence case in most English-language contexts
  • In most programming languages, use one convention per project — camelCase for functions, PascalCase for classes, snake_case for constants
  • kebab-case is the standard format for URL slugs and CSS class names — never use spaces or underscores in URLs
  • camelCase and snake_case strip punctuation — always review the output when converting text that includes special characters
