What is the Case Converter?
Convert text capitalization without retyping it. Choose upper, lower, title or sentence case and copy the output directly from the page.
How to use it
- 1Paste your original text.
- 2Select a capitalization mode.
- 3Copy the transformed text.
How it works
Upper and lower case use JavaScript Unicode casing. Title case capitalizes letters after non-letter boundaries; sentence case capitalizes after a sentence-ending mark.
From draft to heading
“the quick guide” becomes “The Quick Guide” in title mode.
Limitations & notes
- Title capitalization is a simple rule and does not apply publication-specific style guides.
- Locale-specific casing and acronyms may need manual review.
