Case Converter

Flip text between UPPER, lower, Title Case, camelCase, snake_case, and more — click any format to convert and copy instantly.

How It Works

Each case conversion first tokenises your input into words — splitting on spaces, hyphens, underscores, dots, and camelCase boundaries — then joins them with the appropriate separator and applies capitalisation rules. Click any format card to select it and instantly copy the converted result to your clipboard. Everything runs in your browser.
