What this tool can do:

This tool takes any valid decimal input and converts it into hexadecimal format (base-16). It shows the live output with the option to space the characters for easier reading. You can also turn on a step-by-step breakdown to understand exactly how the conversion is performed using repeated division by 16. Every update triggers a flash animation and the tool tracks total output length below the result. It all works on the same page with zero reloads.

Example:

Input:

4095

Settings: Add space between hex digits: OFF, Show conversion steps: OFF

Output:FFF

With Show Steps ON:
