Frequently Asked Questions

Base64 is a binary-to-text encoding scheme that converts binary data into a text string using a set of 64 characters (A-Z, a-z, 0-9, +, /). It's commonly used to encode data for transmission over media that are designed to deal with textual data.

Base64 encoding is useful for embedding binary data in text formats like JSON, XML, or HTML. It's commonly used for data URIs, email attachments, storing binary data in databases, and transmitting binary data over text-based protocols.

Base64 is not a security or encryption mechanism. It's simply an encoding method that converts data to a text format. The original data can be easily decoded by anyone. For security, use proper encryption methods before Base64 encoding.
