What are B64 files and how to open them

Are you having problems opening a B64 file or are you simply curious about its contents? We're here to explain the properties of these files and provide you with software that can open or 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.
