Good to know

  • The first letter of every sentence and every new line is capitalized, and all other letters become lowercase.
  • The language is detected from your text, so rules like the English "I" or Turkish İ and ı are applied only where they belong.
  • Names of people, places and brands are not detected, and German nouns stay lowercase. Check them after converting.
  • Writing systems without capital letters, such as Chinese, Japanese, Korean, Hindi, Arabic and Thai, are left unchanged.

What Is Sentence Case?

Sentence case capitalizes the first word of each sentence while keeping most other words lowercase. Proper nouns, acronyms, and words that require capitalization retain their standard forms.

Example:

Before: HOW TO IMPROVE YOUR WRITING SKILLS

Sentence Case vs. Title Case

Sentence case capitalizes the first word of a sentence, while title case capitalizes most major words in a heading.

  • Sentence case: How to improve your writing skills
  • Title case: How to Improve Your Writing Skills

Use sentence case for straightforward headings, descriptions, and everyday content. Choose title case when your publication or style guide calls for it.

Sentence case is most useful for languages that distinguish uppercase and lowercase letters, such as English, French, and Vietnamese. Languages such as Arabic, Thai, Japanese, and Korean generally do not have the same uppercase and lowercase distinction, so their text may remain unchanged. Mixed-language text can still contain letters that support case conversion.
