How to use the hex converter
Type in any field and the others update as you type. The Numbers section converts a single value between decimal, hexadecimal, binary and octal, including numbers far larger than 64 bits. The Text section converts text to its UTF-8 bytes in hex or binary, and back.
FAQ
How do I convert hex to binary?
Type the hex value into the Hexadecimal field. Each hex digit becomes four binary digits, so FF becomes 11111111. The decimal and octal values update at the same time.
How do I convert hex to text?
Paste the bytes into the Hex bytes field, with or without spaces or 0x prefixes. They are decoded as UTF-8, so accented letters and emoji work too.
Is there a size limit?
Numbers can have up to 1,000 digits, and text up to 200,000 characters.
