Seamless data interoperability. Base64 encoding allows you to represent binary data in clear ASCII text, making it essential for embedding images in CSS, sending email attachments, and passing complex objects through JSON APIs.
The bridge between binary data and text-based protocols.
Base64 works by splitting binary data into groups of 6 bits. Since there are 64 possible 6-bit combinations, they are mapped to 64 ASCII characters.
Encoding data in Base64 results in a roughly 33% increase in size compared to the original binary data. This is the trade-off for text compatibility.
Equal signs at the end of a Base64 string are padding characters used to ensure the encoded text has a length divisible by four.
Originally part of the Multi-purpose Internet Mail Extensions, Base64 is now the global standard for sending attachments over SMTP.
