Number Base Converter

Convert numbers between 8 bases (binary, octal, decimal, hex, base32, base36, base58, custom 2-36) with auto-detection of prefixes (0x, 0b, 0o). Features include bit info (bits, bytes, popcount, power-of-2 detection), interactive binary visualization with bit positions, bitwise operations tab (AND, OR, XOR, NOT, shift left/right), and full ASCII table (printable or all 0-127). Uses BigInt for arbitrarily large numbers.
