Convert text to UPPERCASE, lowercase, Title Case, Sentence case, and more.

Where these characters come from
This is the one family that produces ordinary text. Nothing is substituted; the letters are simply recased, so the output stays fully searchable and accessible.
Worth knowing before you use them
Title case here capitalises major words and lowercases short articles and prepositions, which follows common style guides but not every one. Check the result against whichever guide you are held to.
Where this family earns its place
Case conversion is the practical corner of the site. Title case for headings, sentence case for cleaning up text pasted from elsewhere, upper case for short labels. Because the output is ordinary text, this is the only family with no accessibility or search penalty at all — which makes it the right first choice whenever plain text will do the job.
Every style here, and how each one works
The method matters more than the name: it determines whether your letters are replaced, recased or merely marked, and that in turn decides how the result behaves when pasted into a field that validates its input.
