What is Base64 Encoding?

Base64 encoding is a method used to convert binary data or text into a text-based format using a set of 64 ASCII characters. This encoding is commonly used to safely transmit data over systems that only support text, such as email, URLs, APIs, and web services. It ensures that the data remains intact and uncorrupted without being modified during transfer.

What is Base64 Decoding?

Base64 decoding is the reverse process of converting encoded Base64 data back into its original readable format. This is useful when you receive encoded data from an API or other source, and you need to restore it to its original, usable form.

Why Use Base64 Encoding?

Base64 encoding is widely used in web development and data handling. It helps in embedding images in HTML or CSS as data URIs, transmitting binary data through APIs, and ensuring compatibility across different systems and platforms. It is especially useful when working with JSON data, authentication tokens, and file transfers.
