Base64 Table

Base64 is a way to change binary data into a text format that can be easily shared or stored. This is useful because some systems only handle text, not raw binary data. For example, Base64 is often used to include images in web pages or send data in emails.

Base64 uses 64 characters (uppercase A-Z, lowercase a-z, digits 0-9, and symbols '+' and '/') to represent binary data. This table shows how numbers, their binary forms, and Base64 characters match up.
