Frequently Asked Questions
What is Base64?

Base64 is a group of binary-to-text encoding schemes that represent binary data (more specifically, a sequence of 8-bit bytes) in an ASCII string format by translating the data into a radix-64 representation. It converts binary data into a format that can be easily transmitted or stored in text-based systems, such as email messages or HTML documents, without any loss of information.

What is Base64 used for?

Base64 is widely used for encoding binary data, such as images, audio files, and other non-text data, into a string format that can be sent or stored in text-based systems. It is also used for encoding passwords and other sensitive information, as it provides a simple way to obscure the data and make it more difficult to read by unauthorized parties.
