Frequently Asked Questions
Is this case converter free?
Yes, 100% free with no signup, no limits, and no watermarks.
What is the difference between camelCase and PascalCase?
In camelCase the first word is lowercase (e.g. myVariableName), while PascalCase capitalizes every word including the first (e.g. MyVariableName). camelCase is common in JavaScript; PascalCase is used for class names and React components.
When should I use snake_case vs kebab-case?
Use snake_case for Python variables, database fields, and file names. Use kebab-case for CSS classes, HTML attributes, and URL slugs — since hyphens are preferred in web contexts.
Does this tool work on mobile?
Yes. The converter is fully responsive and works on all phones, tablets, and desktops.
Is my text stored or sent to a server?
No. All conversion happens entirely in your browser using JavaScript. Your text never leaves your device.
