Case Converter

Case Converter rewrites your text in eleven different cases at once: UPPER CASE, lower case, Title Case, Sentence case, camelCase, PascalCase, snake_case, CONSTANT_CASE, kebab-case, aLtErNaTiNg, and InVeRsE. Type once and you get every variation side-by-side with a one-click copy button on each. The tool runs entirely in your browser — your text is never uploaded, logged, or stored. That makes it safe for confidential snippets like internal API names, password hints, customer messages, and draft posts. Common uses include normalizing copy-pasted titles before publishing, fixing accidental caps lock, converting variable names between conventions when porting code between languages, generating slugs and constant names from a feature description, and forcing a sentence case on text scraped from sources that use random capitalization. The Title Case implementation follows the standard rule of capitalizing all major words while leaving short articles, prepositions, and conjunctions ("a", "an", "and", "of", "the") in lowercase, except when they appear at the very start or end. The identifier cases (camel, pascal, snake, kebab, constant) split your text on word boundaries and case transitions, so they work even on input that's already in another case.
