How to use Convert Text to Hex
- 1. Paste your text. Type or paste any text, from a single word to a full message, that you want expressed as raw hexadecimal bytes.
- 2. Set the Separator. Choose what goes between each byte pair in the output, such as a space to produce a familiar hex dump style, or leave it blank for a solid string.
- 3. Copy the hex bytes. Copy the resulting hex byte sequence into a hex editor, a binary protocol payload builder or a script that expects raw byte values.
When to use Convert Text to Hex
Convert Text to Hex encodes plain text as its underlying hex byte values. Reach for it whenever you need to see or transmit the exact bytes behind a string, rather than the characters themselves.
- Building a test payload for a hex editor. You want to insert a specific text string into a binary file using a hex editor, and need the exact byte sequence to paste into the right offset.
- Constructing a raw protocol message. A low-level protocol expects a command string encoded as hex bytes rather than plain ASCII, so you convert the text before assembling the packet.
- Verifying an encoding assumption. You want to confirm exactly how many bytes a short string like Hi takes up and what those bytes are, before relying on that assumption in code.
