Frequently Asked Questions

Q: What is the difference between first-letter and all-letter conversion?
First-letter conversion changes only the first letter of each word. All-letter conversion changes every letter in the entire text.
Q: Will numbers, spaces, and punctuation change?
No. Only letters are affected. Digits, symbols, spaces, and punctuation remain unchanged.
Q: Can I convert long paragraphs and multiple lines?
Yes. You can paste multiple lines or long blocks of text, and the tool will convert case across the entire input.
Q: Is my text uploaded to a server?
No. Processing happens locally in your browser, so your text stays private on your device.
