This online HEX encoder and decoder supports multiple formatting options and allows you to convert text to hexadecimal.
Quickly convert text to HEX or decode HEX to text in your browser with no server upload.
Hexadecimal (HEX) is a base-16 numeral system used to represent binary data in a human-readable format. Each hexadecimal digit represents 4 bits (half a byte), so a byte can be represented by two hexadecimal digits.
When to use HEX encoding: HEX encoding is commonly used in programming and computer science for various purposes, including:
Supported HEX formats for decoding:
Plain
- Simple uppercase or lowercase hex characters (DEADBEEF or deadbeef)With Dashes
- Pairs separated by dashes (DE-AD-BE-EF)With 0x Prefix
- Each byte has 0x prefix (0xDE 0xAD 0xBE 0xEF)With Colons
- Pairs separated by colons (DE:AD:BE:EF)With Spaces
- Pairs separated by spaces (DE AD BE EF)Learn more about hexadecimal encoding at Wikipedia Hexadecimal and character encoding at MDN TextEncoder.
All encoding and decoding is performed locally in your browser - your data never leaves your device.
Essential for low-level programming, system debugging, and analyzing binary data structures in operating systems and embedded systems development.
Critical for network protocol analysis, cybersecurity investigations, and forensic data examination where binary data needs to be inspected in readable format.
This HEX encoder/decoder is valuable for web developers working with binary data, character encoding issues, and data format conversions in modern web applications.
Hexadecimal encoding is universally supported across programming languages with built-in functions and libraries for conversion operations.
Hexadecimal representation follows established industry standards for data interchange, file formats, and protocol specifications.
This tool complements traditional hex dump utilities like hexdump, xxd, and od, providing a browser-based solution for hexadecimal data analysis and conversion.
