Number Base Converter

The base converter handles numeric conversion across bases and text encoding in one place:

• Number conversion: pick a source and target base and convert live, with the value also shown in binary, octal, decimal and hexadecimal
• Huge values: BigInt based, so very large integers convert correctly
• Text to base: encode each character into binary, octal, decimal or hexadecimal, with the reverse direction as well
• Separator: choose what sits between encoded units

Common bases

• Binary (base 2): the machine level, only 0 and 1
• Octal (base 8): 0 to 7, common in Linux file permissions
• Decimal (base 10): the everyday system
• Hexadecimal (base 16): 0 to 9 and A to F, common for colors and memory addresses

When to use it

• Base conversion while programming
• Color values between HEX and RGB
• Address math in networking
• Learning cryptography and encoding
