Hex Encoder FAQ

What's the difference between Hex and Base64?▼

Hex represents each byte as two hex characters (more readable). Base64 is more compact (smaller output) and commonly used for data transfer.

Can it handle Chinese and other non-ASCII text?▼

Yes. Text is first encoded as UTF-8 bytes, then each byte is converted to hexadecimal.

Does it accept input without spaces?▼

Yes. Both 48 65 6C 6C 6F and 48656C6C6F are valid input for decoding.
