How to use Convert Unicode to Hex
- 1. Paste the text you want in hex. Paste the Unicode text you want expressed as hexadecimal. The UTF-8 bytes behind each character are read in order before being converted to base-16 pairs.
- 2. Set a Separator between bytes. Set Separator to the character placed between each hex byte, such as a space or colon, matching the style used in a hex dump, a color code, or a data format.
- 3. Copy the hex string. Copy the hex string and paste it into a hex editor, a byte-level comparison, or code that constructs binary data from a literal hex sequence.
When to use Convert Unicode to Hex
Convert Unicode to Hex shows the hexadecimal byte values behind any text, the same notation used in hex dumps, memory viewers, and low-level debugging tools. Use it when you need to match text against raw bytes shown in hex rather than decimal or binary.
- Matching text against a hex dump. You are reading a hex dump of a file or memory region and want to confirm which bytes correspond to a specific label or string you expect to find inside it.
- Constructing a binary literal in code. A script needs a hardcoded byte array representing a short string, and pasting the hex values directly saves manually looking up each character's UTF-8 encoding.
- Debugging a mangled string in a database. Text pulled from a database shows unexpected characters, and comparing its hex bytes to the hex of the correct string reveals whether an encoding mismatch corrupted it.
- Writing a network protocol example. Documentation for a binary protocol needs to show the exact bytes a text field would contain on the wire, and hex is the standard notation for that kind of reference.

About the Convert Unicode to Hex tool
Convert Unicode to Hex is a free online tool that works entirely inside your web browser. Quickly convert Unicode data to base-16 (hexadecimal). Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 98 Unicode utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
You can shape the output with the Separator setting, and the result refreshes the moment you change it. A worked example further down the page shows exactly what the tool produces for a real input.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
