Frequently Asked Questions

Does it change punctuation?

No — only letters are converted; punctuation, digits and spacing remain identical.

Does it work with other languages?

Yes for every language with cased letters (Latin, Cyrillic, Greek); uncased scripts pass through unchanged.

Is there a length limit?

No practical limit — conversion runs locally and handles very large pastes easily.
