B64 File - opening and understanding
Did your computer fail to open a B64 file? We explain what they are used for and recommend software that we know can open or otherwise handle your .B64 files.
What is a B64 file?
A .B64 file is a Base64 Encoded file. Base64 is a range of encoding schemes used to convert binary data to text. The binary data is encoded into a radix-64 representation. The input consists of 8-bit "characters", where many are non-printable, but the output is printable 6-bit characters. The resulting data is easily transferred across different computer systems, with the downside being that the size is 33% bigger, as every three input bytes are converted to four output bytes.
There are other binary-to-text encoding schemes, and they are all designed to be able to transfer data stored in binary formats across networks and computer systems that only reliably support text content.
Base64 is widely used on the internet to embed binary data like images and icons into HTML and CSS files, and for sending email attachments because old email transfer protocols were only designed to transfer text, not binary data.
How to open B64 files
You will need a program compatible with the specific file you are trying to open, as different programs may use files with file extension B64 for different purposes. We have identified 1 B64 opener for Windows that is compatible with this specific type of B64 file.

While we know of one file format using the .B64 file extension, there may be more. It is widespread that different programs use files with the same file extension for very different types of data. Please let us know if you are aware of a different kind of .B64 file.
