Case Converter
Retyping a paragraph because it was written in all caps, or fixing a headline word by word, wastes time. This case converter lets you paste or type text, pick the capitalization style you need, and copy the reformatted version. It works in your browser and does not require an account.

How to use this tool
- Type your text into the input box or paste it from another document.
- Choose uppercase, lowercase, sentence case, or title case.
- Check the preview of the transformed text.
- Copy the result and paste it wherever you need it.
You can try different options on the same input to compare how each style looks before copying.
How the result is calculated
Each option applies a different capitalization pattern to the letters in your text:
- Uppercase turns every letter into a capital, which suits short labels or emphasis.
- Lowercase removes all capitals, useful as a clean starting point or for casual formatting.
- Sentence case capitalizes the first letter at the start of each sentence.
- Title case capitalizes words according to the tool's own rules, giving headings and titles a consistent look.
The output is shown as a preview so you can review it before copying.
What to keep in mind
Automatic conversion follows patterns, not meaning. Proper names such as people, places, and brands may lose their capitals in lowercase or sentence case, and acronyms like NASA or HTML can end up partly lowercased. Title case uses the tool's rules, which may differ from the specific style guide your publication or school follows. Read through the converted text and correct these cases by hand before using it.
Frequently asked questions
Do I need to sign up to use the case converter?
No. The tool runs in your browser and works without creating an account.
What is the difference between sentence case and title case?
Sentence case capitalizes only the start of each sentence, much like ordinary prose. Title case capitalizes words throughout the text based on the tool's rules, which is typical for headlines.
Why are some names or abbreviations wrong after conversion?
The converter applies a general pattern and cannot recognize every proper name, acronym, or style-guide exception. Review the preview and fix those words manually before copying.
