About Base64 Encoding
What is Base64? Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It uses 64 characters (A-Z, a-z, 0-9, +, /) plus = for padding.
Common Uses: Embedding images in HTML/CSS, encoding email attachments (MIME), storing complex data in JSON/XML, encoding authentication credentials, and transmitting binary data over text-only channels.
Size Increase: Base64 encoding increases the data size by approximately 33% because it uses 4 characters to represent every 3 bytes of data.
