About this tool
This page opens the converter set to hexadecimal output — paste your text, run it and copy the hex bytes, with your choice of separator (space, comma, colon or 0x prefix).
Hex encoding writes each byte of text as two hexadecimal digits — the format you meet in memory dumps, network captures, color codes and low-level debugging.
The full tool also handles Base64 and binary in both directions — everything runs locally in your browser and nothing is uploaded anywhere.
Example. The text Hi encoded as Base64 is SGk=.
