What is title case?

Title case capitalizes major words in a heading, such as “How to Write a Clear Email Subject.” Style guides disagree about short words, hyphenated terms, and prepositions.

What is sentence case?

Sentence case capitalizes the first word and proper nouns, such as “How to write a clear email subject.” It often feels more natural in interface labels and article headings.

Which style should you choose?

Follow your organization’s style guide. For a website, use one style consistently across related headings. Do not capitalize every word automatically if a proper name requires special spelling.

Convert and proofread

Paste text into the Text Case Converter and choose the style you need. Review names, acronyms, and brand capitalization manually afterward.
