What Is the Case Converter Tool?

The Case Converter is a free online tool designed to help you quickly format the capitalization of any text block. If you have ever accidentally typed an entire document with caps lock on, or need to ensure your blog post titles are capitalized correctly, this tool will save you from having to retype everything from scratch.

Features & Formatting Options

Sentence case

Capitalizes only the very first letter of a sentence and leaves the rest lowercase. Perfect for converting block text back into standard readable sentences.

lower case

Converts every single letter in your text into lowercase letters. Removes all capitalization instantly.

UPPER CASE

Transforms all text into capital letters. Great for headlines, warning labels, or emphasizing a specific block of text.

Capitalized Case

Capitalizes the first letter of every single word in your text, regardless of what the word is.

Title Case

Similar to Capitalized Case, but correctly ignores minor words like "and", "the", "of", and "in" according to standard title formatting rules. Essential for blog and essay titles.
