Hex Encoder/Decoder
Convert text to hexadecimal and back. Uses UTF-8 encoding.
About Hex Encoding
Hex encoding represents bytes as pairs of hexadecimal digits. This tool uses UTF-8 for text encoding and decoding, and runs entirely in your browser.
About this Hex Encoder/Decoder
Convert text to hexadecimal (hex) encoding and decode hex back to text. Hexadecimal encoding represents each character as a pair of hexadecimal digits (0-9, A-F). This is useful for debugging, data analysis, low-level programming, and working with binary data. Our tool supports UTF-8 encoding, ensuring proper handling of international characters.
Key Features
Encode text to hexadecimal format
Decode hexadecimal strings back to text
Support for UTF-8 and Unicode characters
Real-time encoding and decoding
Copy hex or decoded text to clipboard
Handle spaces and formatting in hex strings
Works entirely in your browser
No data sent to servers - all processing is local
How to Use
Enter or paste the text you want to encode
Click 'Encode' to convert text to hexadecimal
View the hex output (e.g., '48 65 6C 6C 6F' for 'Hello')
To decode, paste a hex string and click 'Decode'
Use the copy button to copy hex or decoded text
Switch between encode and decode modes as needed
Popular Use Cases
Debug binary data and memory dumps
Analyze file contents in hexadecimal format
Convert text for low-level programming
Encode data for network protocols
Decode hex strings from logs or debugging output
Work with binary file formats
Analyze character encoding issues
Convert text for embedded systems programming
Tips & Best Practices
Hexadecimal uses base-16 (0-9, A-F) to represent bytes
Each byte is represented as two hex digits (00-FF)
Hex strings can include spaces or be continuous
UTF-8 encoding ensures proper handling of Unicode characters
Use hex encoding for debugging binary data
Hex is commonly used in memory addresses and file formats
Remember that hex encoding is not encryption - it's easily reversible
Frequently Asked Questions
What is hexadecimal encoding?
Hexadecimal (hex) encoding represents each byte of data as two hexadecimal digits (0-9, A-F). For example, the letter 'A' is represented as '41' in hex.
How is hex different from binary?
Binary uses base-2 (0s and 1s), while hex uses base-16 (0-9, A-F). Hex is more compact - one hex digit represents 4 bits, so two hex digits represent one byte.
Can I decode hex with spaces?
Yes, the tool handles hex strings with or without spaces. Spaces are automatically ignored during decoding.
Does hex encoding support Unicode?
Yes, our tool uses UTF-8 encoding, which properly handles Unicode characters. Each character is encoded to its UTF-8 byte representation in hex.
