Text Case Converter

A free online text processing tool that convert text between upper, lower, title, camelcase and more. Transform, analyze, and manipulate text instantly in your browser. Formatting text casing correctly is a surprisingly common chore: converting SCREAMING_SNAKE_CASE constants to camelCase for JavaScript, fixing ALL-CAPS headlines, title-casing article headings, or preparing sentence case for email subjects. Most text editors only offer a single toggle, leaving developers and copywriters to retype or manually fix inconsistent casing across hundreds of lines. Seven case modes are available — UPPERCASE, lowercase, Title Case, camelCase, PascalCase, snake_case, and CONSTANT_CASE — each applied instantly with proper handling of abbreviations and compound words. Paste your text and pick a case mode — UPPERCASE, lowercase, Title Case, camelCase, PascalCase, snake_case, or CONSTANT_CASE. The converted text appears instantly; click Copy to grab it. All conversion happens locally in your browser. Your text is never uploaded, making this safe for source code, variable names, and sensitive content.
