Frequently Asked Questions

What is hexadecimal encoding?

Hexadecimal is a base-16 number system that uses digits 0-9 and letters A-F. Each byte of data is represented by two hex characters, making it a compact way to represent binary data in text form.

Can I decode hex strings with spaces or prefixes?

Yes, the decoder handles various hex formats including strings with spaces between byte pairs, 0x prefixes, and other common delimiters. Simply paste your hex data and the tool will process it.

Why does my decoded text show strange characters?

Strange characters usually indicate that the original data was not plain text, or that the encoding was not standard ASCII/UTF-8. The hex might represent binary data, images, or text in a different character encoding.
