The developer toolkit that respects your privacy
BeautiCode is a comprehensive suite of free online tools built for developers, designers, and IT professionals. Our toolkit covers data format conversion (JSON, CSV, XML, YAML), code generation (Java, C#, TypeScript, SQL, Markdown), cryptographic utilities (Hash, AES, Bcrypt, HMAC), QR code generation, and much more.
Privacy-first developer tools.Every converter, formatter, and generator runs entirely in your browser using JavaScript. Their input data is never uploaded to our servers. You can verify this by monitoring the Network tab in your browser's developer tools during any conversion. Our AI Image and Icon Generators are the exception: they require a Google sign-in and run on our servers — see the Privacy Policy for details.
Free to use. Developer tools work immediately with no registration or usage limits. AI Generators are free with a Google sign-in (5 generations per day). BeautiCode is sustained through non-intrusive advertising, allowing us to keep everything accessible to everyone.
Whether you need to format a JSON API response, generate a secure password, decode a JWT token, create a QR code for your business card, or convert colors for a design project — BeautiCode has you covered with a consistent, fast, and private experience.
Input for 90+ developer tools stays on your device. AI Generators use our servers for rate limiting and generation — see Privacy Policy.
