Frequently Asked Questions
What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format by translating it into a radix-64 representation.
Is Base64 encryption?
No. Base64 is an encoding format, not encryption. Anyone can decode a Base64 string back into its original text.
