Frequently Asked Questions
What is Title Case?
Title Case capitalizes the first letter of each major word while keeping minor words (like 'a', 'an', 'the', 'in') lowercase unless they're the first word of the title.
How does Sentence Case work?
Sentence case converts the entire text to lowercase, then capitalizes the first letter of each sentence (after a '.', '!', '?') and the very first letter of the text.
Is my text stored anywhere?
No, all conversions happen in your browser. We don't store or transmit any of your data to our servers.
Can I convert large amounts of text?
Yes, the tool can handle large documents, though very large texts may slightly slow down the conversion process.
Does the converter work with special characters?
Yes, special characters and numbers remain unchanged during conversion. Only letters are affected by case changes.
What's the difference between Alternating and Inverse Case?
Alternating Case alternates between uppercase and lowercase for each character, while Inverse Case flips the case of each character (uppercase becomes lowercase and vice versa).
