This tool runs open-source code from CyberChef by GCHQ (Apache License 2.0). See open-source credits.

Hexdump Decoder converts data between formats in your browser. For a correct result, include offsets only in the supported form.

decoded bytes or text Processing runs in the browser.

Instructions

  1. Provide text or data for this tool.
  2. Choose the hexdump layout.
  3. Compare the output with a known Hexdump Decoder sample.
  4. Keep the original value until the receiving system accepts the result.

Example

Input: a supported hexdump containing 48 69

Settings: Hexdump Decoder: choose the hexdump layout

Result: decoded bytes or text

Limits

  • Hexdump Decoder: different hexdump layouts parse differently
  • Hexdump Decoder: The operation does not detect a different input format automatically.
  • Hexdump Decoder: Processing stays in the browser.

Questions

How do I recover bytes from a hexdump?

Paste the formatted dump with its byte columns intact. The parser attempts to separate byte values from offset and text-preview columns. Compare the recovered length and boundary bytes before using the result.

Does the decoder support every hexdump layout?

No. It recognizes several common layouts through pattern matching. Unusual grouping, missing spacing, or wrapped columns can lead to incomplete recovery. Use plain hexadecimal input with Hex Decoder when you can obtain it.

Why should I check offsets after decoding a dump?

A dump can omit ranges or include display-only address values. The recovered byte sequence does not automatically reconstruct every missing region. Compare consecutive offsets and expected length with the original binary record.
