Frequently asked questions

Does it change numbers or punctuation?

No. Only letters have a case; digits, punctuation, spaces and line breaks are left exactly where they were in the original text.

Why did the German ß stay the same?

ß is already a lowercase letter, so there is nothing to convert; its uppercase form is SS or ẞ depending on the locale.

Can I convert to Title Case?

Not on this page. Lowercase the text first, then capitalise the first letter of each word in your editor, or use a word processor for title case.

Is there a size limit?

No practical one. Even very long documents convert instantly because the work happens on your own device.
