What is Text Case Converter?

A text case converter transforms text between different capitalization formats with a single click. It handles uppercase (ALL CAPS), lowercase (all lower), title case (Each Word Capitalized), sentence case (First word only), camelCase, PascalCase, snake_case, kebab-case, and more. Developers use it for variable naming conventions, writers use it for headlines and titles, and marketers use it for consistent brand formatting. Instead of manually retyping text or writing find-and-replace rules, this tool handles the conversion instantly for any length of text.

How It Works

Enter your text and select the target case format. The tool applies language-aware transformation rules. For title case, it follows standard English capitalization rules — capitalizing major words while keeping articles (a, an, the), conjunctions (and, but, or), and short prepositions lowercase unless they start the title. For programming cases like camelCase and snake_case, it intelligently splits words on spaces, hyphens, and existing case boundaries, then reassembles them in the target format. The conversion handles Unicode characters, accented letters, and multi-word inputs correctly.
