About the Number Base Converter
Type a number in any row – binary, octal, decimal or hex – and the others update instantly. You can also convert to and from any base between 2 and 36. Calculations use arbitrary-precision integers, so very large numbers stay exact.
The bit view shows the binary form as clickable cells labelled by bit position; click any bit to flip it and watch every value update. Choose 8, 16, 32 or 64-bit width to match your data type.
Is anything uploaded? No. All conversion happens in your browser.
