Convert text to hexadecimal or hex to text. Supports UTF-8 encoding.
Frequently Asked Questions
1. What is Hex encoding?
Hexadecimal (base-16) encoding represents binary data using 16 symbols: 0-9 and A-F. Each byte (8 bits) is represented by two hex characters. It is commonly used in programming, HTML colors, and debugging.
2. Does this tool support UTF-8 characters?
Yes. Our Hex converter fully supports UTF-8 encoding, allowing you to encode and decode text with international characters, emojis, and special symbols. The text is first encoded to UTF-8 bytes, then converted to hex.
3. What hex formats are accepted for decoding?
The tool accepts various hex string formats: plain hex (e.g., "48656c6c6f"), space-separated (e.g., "48 65 6c 6c 6f"), and hex with "0x" prefix. All whitespace and common prefixes are automatically stripped before decoding.
4. Is my data stored on your servers?
No. All encoding and decoding is performed locally in your browser. Your data is never transmitted to any server.
