About TextCase

TextCase is a free converter for writers, developers, SEOs, and students who need to switch text between uppercase, lowercase, title, camelCase, snake_case, kebab-case, and more. Everything runs in your browser — nothing is uploaded to a server.

Type or paste text and click Calculate to see every format with a Copy button for each. It is built for speed: no accounts, no waiting, no tracking.

We are a utility, not a style guide. Naming conventions vary by language and team, so always follow your project’s own rules for which case to use.
