After that, divide the resulting string into 8 character groups. Now join all the groups and we will get a 24-character string as below: 010000010100001001000011Ħ. Now, remove the prefix '00' from each group and we get: 010000ĥ. You should get the following binary values: 00010000Ĥ. To do so, find corresponding decimal values in the ASCII table. Now, convert each group from decimal to binary. By doing so, you should get the following indices: Q = 16ģ. For that, map values from the base64 characters table and replace each character with its index. Now, we need to convert the groups into indices. Each group is a base64 character with its own index. Thus, after splitting the string 'QUJD', we get four groups: QĢ. Firstly, split the string letter by letter. Decode it into plain text.įollow the step-by-step instructions below.ġ. Base64 contains the following: Numeric Value:Įxample: Suppose a base64 string is 'QUJD'. Our Base64 Decoder can take any form of data and transform it into plain text. In addition, Base64 is very popular on the World Wide Web and where it embeds image files and other binary assets in textual assets like HTML or CSS files. This system uses 64 digits set that can be represented by 6 bits.

It is used to convert binary data into ASCII (American Standard for Information Interchange) or text format, and vice-versa. Base64 is used in various applications such as email via MIME and storing complex information in JSON or XML format.īasically, base64 is a technique of encoding and decoding. In the world of computer programming, base64 is a set of binary-to-text encoding schemes used to represent binary data in 24-bit sequences that can further be represented in four 6-bit base64 digits. Moreover, it supports almost all the character encoding standards. Also, you can use it to convert base64 data into an image file, hex, or binary form.

It decodes the base64 data and gives results in plain text. Base64 Decode, also known as Base64 Converter, is a free-to-use and simple online tool that does exactly what its name suggests.
