Frequently asked questions
Is my text uploaded anywhere?
No. All conversion happens in your browser — your text never leaves your device.
What is Title Case vs Sentence case?
Title Case capitalizes the first letter of every word. Sentence case capitalizes only the first letter of each sentence.
Does it handle Unicode?
Yes. Letters from any script that has upper/lower variants are handled by the browser built-in toUpperCase / toLowerCase.
