Sentence Case Converter
Automatically capitalize the first letter of each sentence. Perfect for fixing text copied from all-caps or all-lowercase sources.
What is Sentence Case?
Sentence case is a text formatting style where the first letter of the first word in each sentence is capitalized, and all other words remain in lowercase (except proper nouns). It's the standard capitalization used in most written text.

Frequently Asked Questions
Does this tool support all languages?
Our text tools support all Unicode-based languages including English, Hindi, Arabic, Chinese, Japanese, Korean, and more. Some case conversion features work best with Latin-based scripts.
Is there a character limit?
No practical limit for most tools. You can process text from a few characters to tens of thousands of words. Performance depends on your device.
