Hex encoder
Enter text to create a lowercase hexadecimal value.
Encode UTF-8 text as hexadecimal bytes.
About this tool
The Hex encoder converts UTF-8 text into lowercase hexadecimal byte values. Each byte becomes two hex characters, making the underlying data easy to compare and copy. Use it to create a test fixture, inspect how text is stored at the byte level, or compare output between programming languages. Hex encoding is reversible and increases the text length, so it is intended for representation rather than compression or security.
