What is Base64 Encoding?
Base64 is a binary-to-text encoding scheme that converts binary data into an ASCII string format. It's commonly used to encode data that needs to be stored or transferred over media designed to handle text.
Base64 encoding is widely used in web development, email systems (MIME), data URLs, and APIs to safely transmit binary data over text-based protocols.
Common Use Cases
đŧī¸ Data URLs
Embed images and other resources directly in HTML or CSS using Base64-encoded data URLs.
đ§ Email Attachments
MIME email systems use Base64 to encode attachments for safe transmission over SMTP.
đ Authentication
Basic HTTP authentication and many API systems use Base64 to encode credentials.
đ Data Transfer
Safely transfer binary data through JSON APIs and text-based communication channels.
How It Works
Encoding
Base64 encoding takes binary data (or text) and converts it to a string using 64 ASCII characters: A-Z, a-z, 0-9, +, and /. The = character is used for padding.
Decoding
Base64 decoding reverses the process, converting the Base64 string back to its original binary data or text format.
