Base 64 DEcoder / Basic Authorization

With the Free & Online Base64 Decode tool, you can effortlessly decode the encoded Base64 string into a human-readable format or encode the Base64 decoded string.

In simple words, decoding is converting an encoded string into a human-readable format or any useful format for subsequent operations. The process converts the encoded data and files into their original form. It deconstructs the encoded string.

The program or the individual that converts the encoded string into a human-readable format is called a decoder.

Base64 decoding is the reverse operation of the Base64 encoding process. 

To decode the Base64 encoded string. The following steps are the basics behind the algorithm being used.

• Remove any padding characters from the end of the Base64 encoded string.
• Translate each Base64 character back to their six bits binary numbers representation.
• Convert the bits into byte-sized (eight-bits) chunks.
•  Translate the data back to its original format.

To decode the data by using the Base64 decoding scheme. Perform the following steps.

• Open the Free & Online Base64 Decode tool. 
• You can either copy and paste the data that is already Base64 encoded or type out the encoded data in the box here.
• After pasting the already encoded Base64 data in the appropriate box, click on the DEcode button.
• The tool will convert the provided Base64 data into decoded (plain text) format.
• Please copy the resulted data, and paste it into the desired location.
• You can encode the same data by using the Free & Online Base64 Encode tool.

Note: We do not keep a copy of the resulting Base64 decoded form. To save, please copy the resulting Base64 decoded format and it to the desired location for future use if you are satisfied with the results.
