Q: What is Base62 encoding?
A: Base62 encoding uses 62 characters (0-9, A-Z, a-z) to represent data. Similar to Base64 but without special characters (+, /, =), making it URL-safe and filename-friendly.
Q: How does Base62 differ from Base64?
A: Base62 uses 62 characters vs Base64's 64. Base62 avoids special characters, making it URL-safe without encoding. Base64 is more compact but requires URL encoding.
Q: When should I use Base62?
A: Use Base62 for URL slugs, file names, database keys, or any situation where you need compact, URL-safe encoding without special characters.
Q: Is Base62 encoding reversible?
A: Yes, Base62 encoding is completely reversible. Encoded data can be decoded back to its original form without any loss.
Q: How efficient is Base62 encoding?
A: Base62 is about 20% larger than Base64 but eliminates the need for URL encoding. Often more efficient overall for web applications.
