Encoding Detector
Paste any encoded string to automatically detect its encoding type. Supports Base64, URL encoding, HTML entities, Hex, Binary, JWT, and Morse code.
How to Use the Encoding Detector
- Paste an encoded string into the input field.
- The tool automatically analyzes the input and detects possible encodings.
- Each detected encoding shows a confidence level (high, medium, low).
- View the decoded result for each detected encoding.
- Copy decoded values for use in other tools.
About Encoding Detector
When working with encoded data in penetration testing or development, it is often unclear which encoding scheme was used. This tool analyzes the input string against multiple encoding patterns and attempts to decode it using each matching scheme. It detects Base64, URL encoding, HTML entities, hexadecimal, binary, JWT tokens, and Morse code. Each detection includes a confidence level based on how closely the input matches the expected format. All processing happens client-side in your browser.
Frequently Asked Questions
Yes. A string might match multiple encoding patterns. For example, a hex string could also be valid Base64. The confidence level helps you determine which encoding is most likely.
The detector analyzes the top-level encoding only. For nested encodings (e.g., URL-encoded Base64), decode the outer encoding first, then paste the result to detect the inner encoding.
