What the Case Converter Does and Why It Matters
The Case Converter rewrites your text in a different letter case — UPPERCASE, lowercase, Title Case, Sentence case, and more — instantly in your browser. You paste text, pick a case, and copy the converted result.
This matters because text often arrives in the wrong case: a heading typed in all caps, a name in lowercase, or a sentence with random capitalization. Fixing case by retyping is tedious and error-prone, while a one-click converter does it cleanly across any length of text.

Frequently Asked Questions
Is my text stored or sent to a server?
No. All text processing happens entirely within your browser. Your text is never transmitted to our servers or stored anywhere.
What is camelCase used for?
camelCase is commonly used in programming for variable and function names in languages like JavaScript, Java, and C#. It starts with a lowercase letter and capitalizes the first letter of each subsequent word.
What is snake_case used for?
snake_case is popular in Python, Ruby, and other programming languages. It uses lowercase letters with words separated by underscores. It's also common in file naming and URL slugs.
What is kebab-case used for?
kebab-case is primarily used in URLs (hence the name) and CSS class names. It uses lowercase letters with words separated by hyphens.
Does this work with accented characters?
Yes! The tool supports Unicode characters including accented letters (é, ü, ñ, etc.) and many other international characters.
