Frequently Asked Questions
- What is Base62?
- Base62 is an encoding scheme using 62 characters: 0-9, A-Z, a-z. It creates shorter strings than Base64 and is URL-safe since it avoids +, /, and = which need encoding in URLs.
- Base62 vs Base64?
- Base64 uses 64 characters and often adds padding. Base62 uses 62 and needs no padding. Base62 is better for URLs and short identifiers. Base64 is more common for binary data in JSON or MIME.
- When to use Base62?
- Use Base62 for short URLs, database IDs, API keys, or any identifier that should be compact and URL-safe. It's popular in systems like URL shorteners and Bitcoin addresses.
