Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in ASCII string format. It's commonly used to encode data for transmission over text-based protocols.
When should I use URL-safe Base64?
URL-safe Base64 replaces + with - and / with _ to avoid URL encoding issues. Use it when the encoded string will be part of a URL or filename.
