Text Tool

Case Converter

Convert text to upper case, lower case, title case, or sentence case.

About the conversions

Case conversion changes letter capitalization in your browser. It does not rewrite wording, grammar, or punctuation.

What case conversion changes

Case conversion changes capitalization without attempting to rewrite the meaning of the text. Uppercase is useful for labels and emphasis, lowercase can normalize copied text, and title or sentence case can provide a quick formatting pass.

Practical example

Pasting a heading written as “INTRODUCTION TO WEB TOOLS” and choosing sentence case produces a more conventional sentence-style heading. The tool does not know the editorial style guide for a particular publication, so the result may still need manual review.

Limits of automatic capitalization

Names, acronyms, product names, and specialized terms do not always follow simple capitalization rules. Title-case conventions also differ between style guides. Always review important headings after conversion.

Privacy and workflow

The conversion runs in the browser. For sensitive text, still follow your organization’s security rules and avoid pasting confidential information into tools unless you are authorized to do so.

Frequently asked questions

What is case conversion used for?

Case conversion changes capitalization without requiring you to retype the text. It is useful for headings, labels, lists, and cleanup tasks.

Does case conversion change the words themselves?

It changes letter capitalization, not the underlying words. Numbers and punctuation are generally unaffected.

Should I review converted text?

Yes. Automatic conversion cannot know every proper noun, brand name, acronym, or stylistic exception, so review important text before publishing.
