Frequently Asked Questions

Is there any character or word limit?

No. You can paste and convert everything from short single words to multi-chapter documents.

Does this tool preserve spaces and punctuation?

Yes. Text modes (Sentence case, Title Case) preserve punctuation, while code modes (camelCase, snake_case) sanitize spaces into valid programming delimiters.

Is my text stored or sent to a server?

No. All text processing runs directly inside your web browser.

Can I convert text into developer conventions like snake_case or kebab-case?

Yes! The tool transforms spaces and special characters into underscores (snake_case) or hyphens (kebab-case) for clean programming identifiers and URL slugs.
