Convert text between uppercase, lowercase, title case, and more
What is the Case Converter?
Written and maintained by the BitConvert team · Feb 27, 2026
Case Converter rewrites your text into a different letter-casing style without you retyping it. Paste any text and switch it to UPPERCASE, lowercase, Title Case, or Sentence case for everyday writing, or to programming-friendly styles like camelCase, PascalCase, snake_case, and kebab-case. Each option reformats the whole passage in one click.
This saves the tedious work of manually fixing capitalization, whether you accidentally left Caps Lock on, need a headline properly title-cased, or have to convert a phrase into a valid variable or slug name. The developer-oriented cases are especially useful: camelCase and PascalCase suit variable and class names, snake_case fits Python identifiers, and kebab-case matches URLs and CSS classes. The converted result is ready to copy back into your document or code.
