What it is and what it does
pybase62 is a Python module for encoding and decoding integers and byte sequences into base62 format, a numeral system using digits 0–9 and letters a–z and A–Z. It was originally written to shorten URLs in web applications by replacing long decimal integers with compact alphanumeric strings. The module supports both integer encoding and byte array encoding, with byte array support available from version 0.2.0 onward.
The main advantage of base62 over base64 is that it contains no special characters like '/' or '=', making it URL-safe and suitable for embedding directly in URLs without escaping. Additionally, base62 preserves the alphabetical order of the original data when encoded, allowing encoded values to be sorted without decoding. The package has no runtime dependencies and supports Python 3.6, 3.7, 3.8, 3.9, 3.10, and 3.11.
Use it for
- Generate short, URL-safe identifiers for web application URLs instead of long decimal IDs.
- Encode binary data into sortable alphanumeric strings for database keys or cache identifiers.
- Convert large integers into compact representations for logging, analytics, or user-facing IDs.
- Implement sortable encoding schemes where the encoded form maintains the order of the original values.
