Case Converter — FAQs
Is the case converter free?
Yes, it is free forever with no signup, no account and no limits. Convert as much text as you like, from a single word to a full document. There are no premium features and no paywalls — every case style is available to everyone.
Is my text private when I convert it?
Yes. The conversion runs entirely in your browser using JavaScript, so your text never leaves your device. Nothing is uploaded to a server or stored anywhere, which makes the tool safe for private notes, client content and confidential documents.
What do the five case styles do?
UPPERCASE makes every letter capital, lowercase makes every letter small, Title Case capitalizes the first letter of each word, Sentence case lowercases everything then capitalizes the start of each sentence, and aLtErNaTiNg alternates capitals letter by letter for a playful styled look.
Can I convert very long text?
Yes. The converter handles long articles and documents without any problem because it works instantly in your browser. There is no character limit, no queue and no waiting — the result appears in the output box the moment you click a style button.
