How to convert a number between bases (2–36)

1. Enter the value

   "Value" is the number to convert, written in the FROM base. Whitespace is stripped, so `dead beef` and `deadbeef` parse the same. Digits A–Z represent values 10–35, case-insensitive.

2. From base / to base

   "From base" and "To base" are integers between 2 and 36. Common: 2 (binary), 8 (octal), 10 (decimal), 16 (hex), 32 (Base32), 36 (max — uses 0–9 + A–Z).

3. Press Run

   Result is a single `result` field — the value rendered in the target base, lowercase for letters. Invalid digit for the FROM base throws "Invalid digit for source base."

4. Watch the precision limits

   Parsing uses JavaScript `parseInt`, which is limited to 32-bit safe integers in many contexts. Very large numbers (above 2^53) lose precision — use a big-integer tool for those.
