Frequently asked questions

      

        
What format does the hex output use?

        
Each UTF-8 byte is shown as two hexadecimal digits, separated by spaces — for example 48 69 for "Hi".

        
Can it handle non-English characters?

        
Yes. Input is encoded as UTF-8 first, so emoji and CJK characters are converted correctly into multi-byte hex.

        
Is my text uploaded anywhere?

        
No. The conversion runs entirely in your browser; nothing you type leaves your device.
