How to use this tool
Enter text or two-digit HEX byte groups and choose the direction. Spaces can separate bytes, but input cleanup can remove other characters, so use a clean byte sequence.
Results and examples
Hi becomes 48 69 and decodes back to Hi. A Korean syllable needs several bytes; removing one can produce replacement characters or a decoding problem.
Worked example
Hi becomes 48 69 and decodes back to Hi. A Korean syllable needs several bytes; removing one can produce replacement characters or a decoding problem.
Limitations
- Removing non-hex input characters can conceal a typing error.
- Other encodings and arbitrary binary-to-text recovery are not guaranteed.
