About Text Case Conversion

Text case conversion is the process of changing the capitalization pattern of text according to specific rules. Different case styles serve different purposes in writing, from formal documents to creative expression. This tool provides seven different case conversion styles, each following established typographic conventions. Whether you need to fix accidental caps lock mistakes, standardize text formatting, or apply creative styling, these transformations help ensure your text is properly formatted for its intended context.

Available Conversion Styles

Sentence case

Capitalizes the first letter of each sentence and lowercases the rest. This is the standard format for paragraphs and body text in most writing.

"hello world. how are you?" → Hello world. How are you?

lower case

Converts every character to lowercase. Useful for normalizing text, removing accidental capitalization, or creating a casual, modern aesthetic.

"This Is Mixed CASE" → this is mixed case

UPPER CASE

Converts all letters to uppercase. Great for headings, labels, emphasis, or when you need text to stand out without additional styling.

"make this loud" → MAKE THIS LOUD

Capitalized Case

Capitalizes the first letter of each word and lowercases the rest. Commonly used for names, short titles, or when you want consistent word-level capitalization.

"hELLo woRLD from here" → Hello World From Here

aLtErNaTiNg cAsE

Alternates between lowercase and uppercase for each character. This playful style is popular in memes and informal communication, but not suitable for formal text.

"make it fun" → mAkE iT fUn

Title Case

Follows standard English title capitalization rules, capitalizing major words while keeping articles, conjunctions, and prepositions lowercase (unless they're the first word). Perfect for article headlines, book titles, and document headings.

"a guide to better writing" → A Guide to Better Writing

InVeRsE CaSe

Inverts the case of each character—lowercase becomes uppercase and vice versa. Useful for quickly flipping existing capitalization or creating unique stylistic effects.

"InVeRsE CaSe" → iNvErSe cAsE

Frequently Asked Questions

What is a text case converter?

A text case converter is a free online tool that transforms text between different capitalization formats. It can convert text to UPPERCASE (all capital letters), lowercase (all small letters), Title Case (first letter of each word capitalized), Sentence case (first letter of each sentence capitalized), and other formats instantly without manual retyping.

How do I convert text to uppercase?

Simply paste your text into the input field and click the "UPPER CASE" button. All letters will be instantly converted to capital letters. For example, "hello world" becomes "HELLO WORLD". This is perfect for creating headings, emphasizing text, or meeting specific formatting requirements.

What is Title Case and when should I use it?

Title Case capitalizes the first letter of each major word while keeping small words like "a", "an", "the", "in", "of", and "to" in lowercase (unless they're the first word). It's commonly used for book titles, article headlines, and professional documents. Example: "the quick brown fox" becomes "The Quick Brown Fox".
