What is Base64?

Base64 is a binary-to-text encoding system that converts binary data into an ASCII string format that is human-readable. Base64 encoding includes dividing binary data into 6-bit sequences and assigning each sequence a Base64 character.

Because of the extra characters required, Base64 encoding causes a minor increase in data size. Furthermore, because of the processing complexity associated with encoding and decoding processes, Base64 can have little influence on performance.

What is Encoding?

The process of converting data from one form to another is known as encoding. It is a fundamental operation in computing and communication that allows for efficient information storage, transmission, and interpretation.

In the context of data storage, encoding can be used to compress data, which can reduce file size and make storage and transmission more efficient. For example, images and videos are often encoded using compression algorithms to significantly reduce file size without compromising quality.

In the realm of communication, encoding is utilized to ensure compatibility between different devices and platforms.

What is HTML?

HyperText Markup Language (HTML) is the foundation upon which web pages are constructed. It is a standardized markup language that defines the structure and content of web pages. HTML elements are used to mark up the content of a web page, such as headings, paragraphs, images, and links. These elements are then interpreted by web browsers to display the content of a web page in a meaningful and consistent manner.

HTML is a basic and adaptable language for creating a wide range of web pages. It is also a widely accepted language, which means that it can be viewed in the majority of online browsers.

What is an HTML to Base64 Converter?
