About Case Converter

Title case keeps a small set of common English function words lowercase unless they are the first word.

Sentence case uses punctuation and line breaks as simple boundaries; it cannot identify every proper name or abbreviation.

The transformation runs in your browser. This tool does not convert words into programming variable formats.

Frequently Asked Questions

Which changes are available?

Uppercase, lowercase, sentence case, title case, inverted case, and extra-space cleanup.

Is title case grammatically perfect?

No. The tool applies a small set of capitalization rules. Review names, brand styling, and your publication’s own style guide.

Can I undo a change?

Yes. Use Undo immediately after a transformation to restore the previous editor text.
