Frequently Asked Questions
How do I fix text typed in all caps?
Paste it and click "Sentence case" — it lowercases everything, then capitalizes the first letter of each sentence.
What is Title Case?
Title Case capitalizes the first letter of every word, commonly used for headlines and book titles. This tool uses simple per-word capitalization.
Does it work with accented letters?
Yes. Uppercase, lowercase, and inverse conversions use Unicode-aware rules that handle accented Latin characters.
Is my text uploaded anywhere?
No. All conversion happens locally in your browser; nothing is sent to a server.
