How to use Hex dump decode
- 1. Paste hex or text. Spaces and newlines in hex are ignored. Plain text shows a dump on the right.
- 2. Read UTF-8 decode. When input looks like hex, the UTF-8 pane shows decoded text.
- 3. Drop a binary file. Open a file for offset + hex + ASCII columns and a continuous hex line.
About this tool
“Hex dump decode” mixes two jobs: viewing bytes in dump form and reversing hex back to text. This alias emphasizes decode for people who copied hex from logs and need the original string.
Dump layout
Classic dumps show offset, sixteen hex bytes, and an ASCII column. Non-printable bytes appear as dots in the ASCII column.
UTF-8 is not always text
Binary data decoded as UTF-8 may show replacement characters. Treat the ASCII column as a hint, not proof of encoding.
