Frequently asked questions

οΌ‹How do I convert hex to decimal?

Each hex digit is a power of 16. This tool does it instantly β€” enter the hex value and pick 'Decimal' as the output.

οΌ‹Does it accept a 0x prefix?

Yes β€” a leading 0x on hex input is stripped automatically, so both 'ff' and '0xff' work.

οΌ‹Why do developers need this?

Hex is everywhere in crypto: addresses, transaction data, colors and byte values. Fast base conversion saves time.
