What is a case converter?
A case converter is a free online tool that changes the capitalization of your text — to UPPERCASE, lowercase, Title Case or Sentence case — in one click. Writers and editors use it to fix headings, titles and pasted text without retyping anything.
How to use the case converter
- Step 1: Paste or type your text into the box.
- Step 2: Click UPPERCASE, lowercase, Title Case or Sentence case.
- Step 3: Copy the result with one click and paste it wherever you need it.
When each case is useful
- UPPERCASE — warnings, labels and acronyms that need to stand out.
- lowercase — normalizing text before comparing or processing it.
- Title Case — blog post titles, headings and book titles.
- Sentence case — fixing text that was typed in all caps, so it reads naturally.
