Why a case converter saves time

Fixing the case by hand is slow and easy to get wrong, especially for long text. This tool flips everything at once, which is great when you paste text that came in all caps or all lowercase.

Common uses

Use Title Case for headings, Sentence case for normal writing, and lowercase for tags or code. It is a simple helper that keeps your text clean and consistent across documents and posts.
