Free Base Converter (Base 2-36)

Base 36, which uses digits 0-9 and letters A-Z. Higher bases would need additional symbols beyond standard alphanumerics.

Convert source to decimal first (multiply by powers of source base), then convert decimal to target (divide by target base, read remainders). This tool automates both steps.

A=10, B=11, C=12... Z=35. For bases 11-36, letters extend beyond the 10 digits. Case does not matter: a=A=10.

Base 36 creates short representations of large numbers using all alphanumeric characters. URL shorteners and compact IDs sometimes use it.

Binary (base 2). Computers use hexadecimal for human readability since it converts easily to binary (each hex digit = 4 bits).

Base64 encoding exists but uses a different system - it encodes binary data to text rather than representing numbers positionally. Traditional positional bases max at 36 with alphanumerics.
