Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is commonly used to encode data that needs to be stored or transferred via text-based protocols.
Is Base64 encoding the same as encryption?
No, Base64 is not encryption. It is simply an encoding scheme that can be easily reversed. Anyone can decode Base64 data without a key.
When should I use URL-safe Base64?
Use URL-safe Base64 when the encoded data will be part of a URL or filename. It replaces + with - and / with _ to avoid URL encoding issues.
