Base62 to Binary Conversion Principle
① Base62 → Decimal: Expand by place value (62^n)
② Decimal → Binary: Repeated division by 2, collect remainders
③ Use decimal as intermediate bridge for accurate conversion
Base62 uses 0-9, A-Z, and a-z (case-sensitive) to represent values 0-61. Converting to binary first converts to decimal as an intermediate step.
⚠Base62 is case-sensitive! 'A' (value 10) is different from 'a' (value 36). Only use 0-9, A-Z, a-z characters.
What Is Base62 to Binary Conversion?
Base62 to binary conversion transforms a base62 (62-character) alphanumeric string into a binary (2-character) representation, using decimal as an intermediate bridge.
Base62 Character Set
0-9 (0-9), A-Z (10-35), a-z (36-61). 62 total characters, case-sensitive. Compact representation for large numbers.
Binary Character Set
0 and 1 only. 2 total characters. Fundamental in computer science and digital systems.
Place Value Expansion
Each digit d_i at position i (rightmost = 0) contributes d_i × 62^i to the decimal value. Sum all terms for total decimal.
Repeated Division
Divide decimal by 2, collect remainders. Read remainders from last to first to get binary result.
Base62 is a positional numeral system with a radix of 62. It uses 0-9, A-Z, and a-z to represent values 0-61. Base62 is commonly used for URL shortening and compact identifiers.
How do I convert base62 to binary?▼
First convert base62 to decimal by expanding each digit by its place value (62^n), then convert the decimal result to binary using repeated division by 2 and collecting remainders.
What characters are used in base62?▼
Base62 uses digits 0-9 (0-9), uppercase letters A-Z (10-35), and lowercase letters a-z (36-61). Case-sensitive: A ≠ a with different values.
Why use base62 for URL shortening?▼
Base62 produces the shortest possible alphanumeric strings for large numbers, using both cases of letters, making it ideal for compact URLs and identifiers.
