Convert Text to Sentence Case

Transform text into natural, readable sentence case with our free online converter. Sentence case capitalizes only the first letter of each sentence, making it look like standard written prose.

**What is Sentence Case?**

Sentence case is the standard capitalization used in everyday writing. Only the first letter of each sentence is capitalized (along with proper nouns). For example, "THIS IS A TEST. HERE IS ANOTHER." becomes "This is a test. Here is another."

**When to Use Sentence Case:**
- Body text in articles and blog posts
- Email content and messages
- Product descriptions
- Social media posts
- Document paragraphs
- Converting all-caps text to readable format

**How It Works:**

Our sentence case converter intelligently detects sentence boundaries (periods, exclamation marks, question marks) and capitalizes the first letter following each. The rest of the text is converted to lowercase for a natural, readable result.

**Perfect for Fixing All-Caps Text:**

We've all received emails or documents written entirely in capital letters. They're hard to read and can feel aggressive. Our tool instantly transforms all-caps text into comfortable, easy-to-read sentence case.
