FAQ

Does it keep punctuation and numbers?

Yes. Only the letter casing changes; punctuation and numbers remain the same.

What’s the difference between Title and Sentence case?

Title Case capitalizes significant words; Sentence case capitalizes only the first letter of each sentence.

Will multiple spaces be collapsed?

By default, the tool may normalize spacing with trimming. Enable “Preserve multiple spaces” to keep them.
