Sentence Case Converter – Free Online Tool to Capitalize Sentences Instantly

Welcome to our Sentence Case Converter, a free and reliable online text tool designed to make your writing polished and consistent. Whether you paste messy content from multiple sources or draft a quick note, this Sentence Case Converter capitalizes the first letter of every sentence and normalizes the rest, so your copy reads naturally and professionally.

What Does a Sentence Case Converter Do?

A Sentence Case Converter automatically changes text so that the first letter of each sentence is uppercase and the remaining letters are lowercase (unless proper nouns or acronyms require different casing). This is especially useful when text has inconsistent capitalization, multiple line breaks, or mixed-case input.

Example:
input:  this is a test. here is another line.
output: This is a test. Here is another line.
