convert text to sentence case online

Why Use a Sentence Case Converter?

We have all been there: you look up at your screen only to realize you’ve typed an entire paragraph with CAPS LOCK turned on. Or perhaps you’ve received a document where the capitalization is inconsistent and messy. Manually fixing every sentence is tedious and prone to human error. Our tool allows you to convert text to sentence case online in seconds, ensuring your writing looks professional and polished.

How the Sentence Case Logic Works

Sentence case is the standard format for most English writing. It involves capitalizing the first letter of the first word of a sentence and keeping the rest in lowercase (except for proper nouns). Our algorithm intelligently detects sentence endings—such as periods, exclamation marks, and question marks—and ensures the following word begins with a capital letter. For even more detailed text analysis, you might want to use our Sentence Counter to track your document's structure.

Fix Capitalization for Social Media and Emails

Whether you are drafting a professional email or cleaning up a caption for a Facebook post, proper capitalization matters. Writing in all caps can come across as "shouting," while all lowercase can look lazy. By using a text formatter, you maintain a balance that is easy to read and respectful to your audience.

A Versatile Tool for Writers and Students

Students often copy notes from various sources that have different formatting styles. Our converter helps unify those notes instantly. Beyond just sentence case, you can toggle between uppercase for headings or capitalized case for titles. If you are working on a blog post or article, you can also use our Title Case Converter specifically for your headlines.

Your text never touches our servers. It is fast, secure, and completely free to use as many times as you need.
