Description
Convert text to Title Case (8 style guides), UPPERCASE, camelCase, snake_case, and more — right where you're typing. Transform Case brings the same conversion engine from transformcase.com into your browser — right-click any selected text, or open the toolbar popup, and convert it without leaving the page. WHAT IT DOES • Title Case, done correctly — 8 style guides: AP, Chicago, APA, MLA, NY Times, Wikipedia, Bluebook, and AMA. Each has different rules for which words get capitalized; this gets them right instead of guessing. • Every common case — Sentence case, UPPERCASE, lowercase, Capitalized Case, camelCase, PascalCase, snake_case, kebab-case, CONSTANT_CASE, dot.case, slug-url, aLtErNaTiNg, and InVeRsE. • Works right where you're typing — select text in Gmail, Google Docs comments, a CMS editor, a code review tool, or any text field, right-click, and the converted text replaces your selection in place. No copy-pasting into a separate tab. • Custom terms — teach it your brand names, usernames, or any word it doesn't already know, so they're capitalized correctly every time. Saved locally in your browser. • Keyboard shortcuts — Alt+U for UPPERCASE, Alt+L for lowercase, Alt+T for Title Case, Alt+S for Sentence case. • Built-in proper-noun dictionary — iPhone, GraphQL, NASA, PostgreSQL, and thousands more stay in their correct form even mid-sentence. HOW TO USE IT 1. Select any text on any page. 2. Right-click → Transform Case → pick a conversion. 3. Done — the text is replaced in place if you're in an editable field, or copied to your clipboard if the page itself is read-only. Or click the toolbar icon for the full converter: paste text, pick a mode, copy the result. PRIVACY Everything runs locally in your browser. Your text is never sent to any server — not ours, not anyone's. Your style preference and custom terms are stored only in your browser's local extension storage and are never transmitted anywhere. From the team behind transformcase.com — a case converter built for writers, editors, and developers who care about getting the details right.
