NuToolz Developer Tools are built for programmers, engineers, and tech professionals who need quick utilities without leaving the browser. Format and validate JSON with syntax highlighting, encode and decode Base64 text with Unicode support, generate cryptographically secure passwords, or create customizable QR codes. Every tool processes data locally in your browser — nothing is ever sent to a server, making them safe for handling sensitive information like API keys and credentials. These tools complement your development workflow whether you are debugging an API response, preparing data for transmission, or generating secure access credentials. No installation, no account, no limits. All developer tools are responsive and work on any device.
