Free Security & Encoding Tools Online

Working with encoded data and secure credentials requires tools you can trust. Our free online security and encoding utilities handle Base64 conversion, URL encoding, and password generation entirely in your browser — your sensitive data never transmits to any server. This client-side approach is essential when working with authentication tokens, encoded API payloads, or generating passwords for important accounts. Encode text and files to Base64 for embedding in JSON or HTML, decode Base64 strings to inspect their contents, or properly encode URLs with special characters for safe transmission. The password generator creates cryptographically secure passwords using your browser's random number generator, with customizable length and character options. These tools are perfect for developers debugging encoded data, security professionals testing systems, or anyone who needs strong passwords without trusting third-party generators. Completely free, private by design, and available whenever you need them.
