Sentence Case Converter
Convert text to sentence case with proper capitalization at the start of sentences.
Used by: The New York Times, The Guardian, most academic writing, and anyone who thinks title case looks shouty.
What Is Sentence Case?
First letter up, rest down. Except proper nouns stay capitalized. And acronyms. And sometimes brand names have weird casing (iPhone, eBay) that you might want to preserve.
Quick Start
- 1
Paste your text
Works with any length — single headline or entire paragraphs.
- 2
Get results instantly
First letter capitalized, rest lowercase.
- 3
Review proper nouns
Fix any names or acronyms that need re-capitalizing.
When to Use Sentence Case
- Academic papers and journals
- News headlines (many publications)
- Email subject lines (more casual feel)
- UI text and button labels
Heads Up
Watch out: Converting to sentence case will lowercase proper nouns too. "APPLE ANNOUNCES IPHONE" becomes "Apple announces iphone" — you'll need to fix "iPhone" manually.
