There are two built-in functions in JavaScript for encoding and decoding raw binary data into Base64 strings. In this article, you'll learn how to encode and decode Base64 strings in JavaScript.
You first encode the binary file into a textual format, preferably ASCII. It only transforms the binary data into an ASCII character set that is extremely useful for transferring obfuscated strings over the network.įor instance, a simple example is sending an image or any other binary file to an email server that typically expects textual data. It is important to remember that Base64 is not an encryption or compression scheme. Base64 makes sure that the binary data doesn't change during transportation. It is commonly used for encoding and transporting data over media incompatible with transferring binary data. Base64 is a widely used binary-to-text encoding scheme that transforms binary data into an equivalent ASCII character set by translating it into a radix-64 representation.
