What Generate Random Hex Numbers can do:

Each output line is a standalone hex value using characters 0–9 and A–F (or a–f). The length is up to you go with something short like 2 digits for compact codes, or stretch it to 8+ for simulating hash chunks, color codes, or memory values. By default, values are shown in uppercase.

In the Options box, Hex Length controls the number of characters per value. Amount to Generate defines how many values you want in total. And the Use uppercase letters toggle determines whether your hex values show up like 2F8B or 2f8b. The output updates instantly, and the counter helps track exactly how many values you’ve generated.
