Frequently Asked Questions (FAQ)

Q: Will using this tool affect my text formatting like bold or italic?

A: No, this is a plain-text formatter. It modifies the capitalization of characters but strips away rich-text styles. It is ideal for pasting clean text directly into code editors or word processors.

Q: Is there a character limit for the text conversion?

A: There is no hard limit imposed by our software. Since the computation happens locally on your computer, it can easily handle large documents, books, or datasets within seconds.

A: Yes. Punctuation, symbols, and emojis remain untouched, while any international alphabetical letter will be correctly converted according to your chosen style.
