About Hex Decoder

Hex Decoder is a free online tool that converts hexadecimal (base-16) data back into human-readable text. Hexadecimal encoding is widely used in programming, networking, and data analysis to represent binary data in a compact, readable format. Whether you are inspecting network packets, debugging encoded payloads, analyzing file headers, or reversing hex-encoded API responses, this tool lets you instantly decode hex strings into plain text, binary, decimal, Base64, or ASCII code representations.

The tool supports multiple hex input formats including plain continuous hex, 0x-prefixed values, space-separated pairs, and colon-separated notation commonly used in MAC addresses and certificate fingerprints. You can choose between UTF-8, ASCII, and ISO-8859-1 (Latin-1) character encodings to correctly interpret international text and special characters. All processing happens entirely in your browser using JavaScript — no data is ever sent to a server, ensuring your information stays completely private and secure.

Frequently Asked Questions

What is Hex Decoder? expand_more
Hex Decoder is a free online tool that converts hexadecimal (base-16) strings into readable text. Each pair of hex digits represents one byte — for example, "48 65 6C 6C 6F" decodes to the text "Hello". It is commonly used by developers, network engineers, and security analysts to inspect and interpret hex-encoded data.
What input formats are supported? expand_more
The tool supports four hex input formats: Plain Hex (continuous string like "48656c6c6f"), 0x Prefixed (values like "0x48 0x65 0x6C"), Spaced Hex (pairs separated by spaces like "48 65 6C"), and Colon Separated (pairs separated by colons like "48:65:6C"). Select the matching format from the dropdown before decoding.
What output formats are available? expand_more
The decoded data can be viewed in five formats: Text (the decoded human-readable string), Binary (8-bit binary representation of each byte), Decimal (numeric decimal value of each byte), Base64 (the bytes re-encoded as a Base64 string), and ASCII Codes (decimal value with the corresponding character label for each byte). Switch between them using the output tabs.
Is my data secure when using this tool? expand_more
Yes, completely. All hex decoding is performed locally in your web browser using JavaScript. No data is transmitted to any server, stored, or logged. Your hexadecimal input and decoded results remain entirely on your device, making it safe to use with sensitive or proprietary data.
