About Encoding Tools
Encoding Tools provides essential encoding and decoding utilities for web developers and security engineers. Convert text to Base64, URL-encode query parameters, and translate strings to hex — all in your browser without any data leaving your device.
Use the Base64 tab to encode text for embedding in JSON payloads or basic auth headers, or use File → Base64 to convert images directly to Data URI format for embedding in CSS or HTML. The URL tab handles both encoding query string values and parsing complete URLs into their components — protocol, host, path, and query parameters. The Hex tab converts between text and hex byte strings, useful for binary protocol debugging.
All encoding and decoding operations run entirely in your browser. No text, files, or secrets are transmitted to any server.
