Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format using 64 distinct characters (A-Z, a-z, 0-9, +, /). It is commonly used for transmitting media or payload data safely across systems that handle text.
Is Base64 considered encryption?
No, Base64 is an encoding mechanism, not encryption. Anyone can decode a Base64 string back to its original plain text without a secret password.
