?Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format, commonly used in data URIs and APIs.
Is Base64 the same as encryption?
No. Base64 is encoding, not encryption. It is easily reversible and should not be used for securing sensitive data.
What is URL-safe Base64?
URL-safe Base64 replaces + with - and / with _ to make the encoded string safe for use in URLs without percent-encoding.
