help_outline About Base64 Encoding
What is Base64?
Base64 is an encoding scheme that converts binary data into ASCII text format. It's commonly used to transmit data over channels designed to handle text, ensuring data remains intact without modification.
How Base64 Works
- looks_one Converts binary data to 6-bit groups
- looks_two Maps each 6-bit group to ASCII characters
- looks_3 Uses A-Z, a-z, 0-9, +, and / characters
- looks_4 Adds padding with '=' when needed
Common Use Cases
- email Email attachments (MIME encoding)
- image Embedding images in HTML/CSS
- code Data transmission in APIs
- storage Storing binary data in text formats
- security Basic authentication headers

Important Note:
Base64 is an encoding method, NOT encryption. It can be easily decoded by anyone. Do not use it for sensitive data protection.
