Frequently asked questions
Can I convert ALL CAPS back to normal?
Yes. Paste the text and choose Sentence case to restore normal capitalisation, or lowercase to remove all capitals.
What is the difference between Title Case and Sentence case?
Title Case capitalises the first letter of every word (great for headings); Sentence case capitalises only the first letter of each sentence (great for body text).
Does it change my numbers or punctuation?
No. Only letters are affected; digits, punctuation and spacing are left exactly as you entered them.
Is my text uploaded?
No. The conversion runs entirely in your browser. Your draft stays in tab memory during internal navigation and is discarded when you reload or close the tab.
