Is my text sent to a server?

No. All case conversion runs 100% in your browser. Your text never leaves your device.

What is the difference between camelCase and PascalCase?

camelCase starts with a lowercase letter and capitalizes each subsequent word (e.g. myVariableName). PascalCase (also called UpperCamelCase) capitalizes every word including the first (e.g. MyClassName). camelCase is standard for variables and functions in JavaScript/Java; PascalCase is standard for class names.

What is snake_case used for?

snake_case uses underscores between words with all lowercase letters. It is the standard naming convention in Python (variables, functions, modules), Ruby, and SQL column names. SCREAMING_SNAKE_CASE (all caps) is used for constants in most languages.

What is kebab-case used for?

kebab-case uses hyphens between words with all lowercase letters. It is the standard for CSS class names, HTML attributes, URL slugs, and file names in web projects. It cannot be used for variable names in most programming languages since hyphens are subtraction operators.

ROT13 is a simple letter substitution cipher that rotates each letter 13 positions in the alphabet. It is its own inverse — applying ROT13 twice returns the original text. It is used for hiding spoilers and puzzle answers in online communities, not for security.
