Sentence Case Converter
Convert text to sentence case, capitalising the first word after each full stop while leaving acronyms and the pronoun I untouched. Usual style for web headings.
How to use
- Paste your text into the box.
- Read the sentence-cased result.
- Copy it back into your document.
Sentence case capitalises only the first word of each sentence and lowercases the rest. It is the house style of most user interface writing, because it reads faster than title case in an interface.

Questions about sentence case converter
- Why is I still capitalised?
- The pronoun I is always capitalised in English, so it is a deliberate exception rather than an oversight.
- Are acronyms preserved?
- Short all-capitals tokens such as API or ID are left as they are.
- Should blog headings use sentence case?
- Yes for interface text and usually for web headings, since sentence case is faster to scan.
