Frequently asked questions
Does Title Case understand small words?
Our Title Case capitalises the first letter of every word. For style-guide aware title casing (lowercasing 'of', 'and', etc.), edit the few exceptions manually after.
What does Sentence case do?
It lowercases the entire text, then capitalises the first letter of each sentence (after a period, exclamation mark, or question mark).
Are line breaks preserved?
Yes. Every line break and paragraph is kept exactly as you pasted it. Only the letters change case.
Is there a size limit?
Up to 2 MB of text per job, which is hundreds of thousands of lines for typical content.
How long is the result kept?
Your converted .txt is auto-deleted after 7 days. Re-download is available during that window via the secure link.
