Paste your text and switch it to UPPERCASE, lowercase, Title Case, Sentence case and more in one click. Everything stays in your browser.
Conversion happens entirely in your browser with JavaScript. Nothing you type or paste is uploaded, stored or seen by anyone — close the tab and it's gone.
Typed a whole paragraph WITH CAPS LOCK ON? Click Sentence case to fix it in one go — it lowercases everything, then re-capitalizes the first letter of each sentence.
Unlike a plain "capitalize every word", Smart Title Case follows headline style: small words like a, an, the, of, in, to stay lowercase unless they start or end the title.
camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE convert each line separately — handy for renaming variables, file names, CSS classes and database columns.
Every conversion keeps a copy of your previous text, so you can compare results or step back if you clicked the wrong button. Copy or download the result when you're happy.
