Decode Base64 to ASCII Converter

What Is ASCII?

ASCII is a character encoding standard used for representing text in computers and electronic devices. Developed in the 1960s, it encodes 128 specified characters into seven-bit binary integers. ASCII covers English letters (both uppercase and lowercase), digits (0-9), punctuation symbols, and control characters like newline or carriage return.

ASCII serves as a foundation for most modern character encoding schemes and is widely used in computer programming, data processing, and digital communication. ASCII's simplicity and universal adoption make it a critical aspect of text representation in the digital world.

What Is Base64?

Base64 is an encoding scheme used to represent binary data in an ASCII string format. It is particularly useful in encoding data that needs to be stored and transferred over media designed primarily for textual data.

Base64 works by dividing the input data into 6-bit blocks, then representing each 6-bit block with a corresponding character from a set of 64 characters (including A-Z, a-z, 0-9, '+', and '/'). It is commonly used in web development for encoding images and other binary files into a form that can be embedded in HTML and CSS, as well as in email to encode attachments.

How to Use the Base64 to ASCII Code Converter

Enter your base64 into the "Input" text box and see the ASCII code conversion in the "Output" box. The output will show the ASCII codes (decimal number) for whatever input you provided. To see how these are translated, see the table below.
