Frequently Asked Questions

Is it secure to use this converter for sensitive text?
Yes, absolutely. All processing is done locally in your browser using JavaScript. No text is ever uploaded to any server, making it safe for passwords, code, or personal documents.
What is the difference between Title Case and Capitalized Case?
Capitalized Case capitalizes every single word. Title Case is more sophisticated; it leaves minor words (like 'and', 'the', 'of') in lowercase unless they start the sentence, following standard editorial guidelines.
Can I save my conversion history?
We don't automatically track history for privacy reasons, but you can manually 'Save as Note' to keep any transformation permanently in your local notes library.
