FAQ
Why is hexadecimal used?
Hexadecimal is used in computing because it is a shorter and more readable way to show binary data. Each hex digit stands for a four-digit binary number, so it is easier to work with large binary values in hex. It is often used for memory addresses and color codes.
Is hex encoding the same as encryption?
No, hex encoding is not encryption. It is just another way to represent data and can be easily changed back. It does not provide any security. For that, you should use something like AES encryption.
Why is the hex output longer than the input?
Each character in your text is one byte of data. In hexadecimal, each byte is shown as two hex characters. So, the hex string will be twice as long as the original data in bytes.
