Hex Decode

What is Hex Decode?

Hexadecimal (Hex) encoding represents binary data using base-16 notation with characters 0-9 and A-F. Each byte is represented by exactly two hexadecimal digits, making it straightforward to read and debug. It's the most common way to display raw binary data in a human-readable format.

How to Use Hex Decode

1. Paste your Hex-encoded text into the input field. 2. The decoded result appears instantly in the output field. 3. Click "Copy" to copy the decoded text to your clipboard. 4. Use "Clear" to reset and start over.

When to Use Hex Decode

Use Hex decoding to convert hexadecimal strings back to text, read color values, or extract binary data from hex dumps.

How Hex Decode Works

Each byte (8 bits) is split into two 4-bit nibbles. Each nibble (0-15) is represented by a single hex character (0-9, A-F). For example, byte 255 becomes "FF", and byte 0 becomes "00". This doubles the data size but maintains a 1:1 byte-to-representation ratio.

Common Use Cases

• Debugging binary data
• Color codes in CSS/HTML
• Memory addresses
• Hash digest display (MD5, SHA)
• MAC addresses
• Binary file viewers/editors
• Character encoding inspection
