Frequently asked questions

What is Title Case?

Title Case capitalizes the first letter of every word, which is commonly used for headings and titles.

What's the difference between camelCase and snake_case?

camelCase joins words with no spaces and capitalizes each word after the first (myVariableName), while snake_case joins them with underscores in lowercase (my_variable_name).

Can I convert text for code identifiers?

Yes. camelCase, snake_case and kebab-case are designed for variable names, file names, slugs and other identifiers.

Is my text uploaded anywhere?

No. All conversion happens locally in your browser, so your text never leaves your device.
