Frequently Asked Questions (FAQ)

Is my text data secure and private?

Yes! The case conversion happens 100% locally in your web browser using JavaScript. We never upload your text to an external server, making it completely safe for sensitive documents, code, or personal emails.

Why use this tool instead of Microsoft Word?

While Word has a basic toggle case function (Shift + F3), it does not support programmer cases like camelCase, snake_case, or kebab-case. Furthermore, using a lightweight web tool is much faster than opening a heavy desktop application.

What is the difference between Title Case and Sentence Case?

Sentence case only capitalizes the very first letter of the sentence, just like a normal paragraph. Title Case capitalizes the first letter of almost every word in the sentence, which is typically used for blog titles and headlines.

Can I convert kebab-case back to normal text?

Currently, the case converter is designed to turn normal sentences into code cases. To convert kebab-case back to normal text, you can use our Replace Text tool to replace hyphens with spaces, and then use this tool to apply Sentence case.
