Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data that needs to be stored or transmitted over media designed for text.
URL-safe Base64 replaces '+' with '-', '/' with '_', and removes padding '=' characters. This makes the encoded string safe to use in URLs and filenames.
