FAQ
What is Base64?
Base64 is an encoding scheme that represents binary data as ASCII text using 64 different characters. It's commonly used for embedding images in web pages, encoding email attachments, and transmitting binary data over text protocols.
Is Base64 encoding secure?
Base64 is encoding, not encryption. It makes binary data safe for text transport but provides no security. Anyone can decode Base64. Don't use it to protect sensitive data.
