What the buttons do
UPPERCASE and lowercase follow your browser. Title Case capitalizes the first letter of each word. The URL line is lowercase, without marks, joined by hyphens.
How to change case or make a slug
- Type the value: Paste the heading, the filename, or the sentence.
- Pick the source unit: Tap UPPERCASE, lowercase or Title Case — whichever you need.
- Read every conversion: Copy the result, or copy the URL line if you need an address.
