Free Base64 encode and base64 decode utility by Apna tutorials. You can use this online tool to convert binary data to base64 format or to decode a base64 encoded data to binary data
URLs can only be sent over the Internet using the ASCII character set. Since URLs often contain characters outside the ASCII set, the URL has to be converted into a valid ASCII format. Base64 encoding is a way to convert binary data in an ASCII string format.
The term Base64 refers to a specific MIME content transfer encoding. Base64 encoding represent binary data in an ASCII string format . Base64 encoding is basically a way of encoding arbitrary binary data in ASCII text. It takes 4 characters per 3 bytes of data, plus potentially a bit of padding at the end.
Essentially, each 6 bits of the input is encoded in a 64-character alphabet. The "standard" alphabet uses A-Z, a-z, 0-9 and + and /, with = as a padding character. There are URL-safe variants.
Base64 can be used in number of useful context. Some of them are:
