Frequently asked questions
What is the difference between title case and sentence case?
Title Case capitalizes the first letter of most words (used for headlines). Sentence case only capitalizes the first letter of each sentence, like normal prose.
Is my text sent to a server?
No. All conversion happens locally in your browser using JavaScript, so nothing is uploaded or stored.
Is there a limit on how much text I can convert?
There is no fixed limit — it comfortably handles anything from a word to many pages of text.
