Frequently Asked Questions

What is a case converter?

A case converter changes the capitalization of text. It can convert text to UPPERCASE, lowercase, Title Case, camelCase, snake_case and many other formats used in writing and coding.

What is camelCase and when is it used?

camelCase writes compound words with no spaces, where each word after the first starts with a capital letter (e.g. helloWorld). It is widely used in JavaScript, Java and other programming languages for variable names.

What is snake_case?

snake_case uses underscores between words in lowercase (e.g. hello_world). It is commonly used in Python, Ruby and database column names.

Is my text saved or sent to a server?

No. All conversion happens entirely in your browser using JavaScript. Your text never leaves your device.
