Frequently Asked Questions
- How is camelCase different from PascalCase?
- Both join words without spaces. camelCase keeps the first letter lowercase ("helloWorld") while PascalCase capitalizes every word including the first ("HelloWorld"). camelCase is common for variables, PascalCase for classes and types.
- Is the random string generator cryptographically secure?
- It uses the browser's `crypto.getRandomValues` API, which is suitable for tokens, slugs, and most security-adjacent use cases. For long-term secrets like passwords, prefer the dedicated Password Generator tool.
- Does it count multi-byte characters correctly?
- Yes. The byte counter reports UTF-8 bytes, while the character counter reports JavaScript code units. Emojis and CJK characters are handled.
- Can I deduplicate or sort lines?
- Yes. The Lines section lets you sort alphabetically, sort by length, deduplicate, or reverse line order in one click.
- Does any data leave my browser?
- No. Every transformation runs locally with no network requests.
