Switch text between seven letter cases in one click.
Case Converter transforms your text into UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case or kebab-case with a single click, then copies the result to your clipboard. It works on anything from headlines to variable names. It all runs on your device.
Type or paste your text into the box above.
Click a case button (UPPERCASE, lowercase, Title Case, Sentence case, camelCase, snake_case or kebab-case) and the text converts in place.
Click Copy to put the converted text on your clipboard, ready to paste anywhere.
This tool requires a Pro subscription. The conversion itself still happens on your device.
Title Case capitalizes the first letter of every word, the style used for headlines. Sentence case capitalizes only the first letter of each sentence (after a period, exclamation mark or question mark), the way normal prose is written.
They are programming and web conventions: camelCase is common for variable names in JavaScript, snake_case for Python identifiers and database columns, and kebab-case for URL slugs and CSS class names. Each strips punctuation and joins the words accordingly.
No. Every conversion happens on your device, so your text stays with you.
