Hexadecimal converter
For converting single numeric values, use the binary/decimal converter. This tool converts hex byte strings to and from plain text.
What is Hexadecimal converter?
This converts between plain text and its hexadecimal byte representation — the format you'll see in packet captures, memory dumps, and low-level debugging output, where each byte of text is shown as two hex digits.
How to use it
Type text on one side to see its hex bytes, or paste space-separated hex bytes on the other side to decode them back into text. Handles full UTF-8, not just ASCII.
Example
Text: Hi
Hex: 48 69
