# What is Base64 encoding?

Base64 encoding is designed to make binary data survive transportation through layers that are not 8-bit clean, such as mail bodies. In standart 8-bit ASCII character set, there are 256 characters that are used to format text. However, only a fraction of these characters are actually printable and readable. Base64 encoding gives as a way to convert (encode) unreadable characters into readable ones, transport them (send in an email), and decode them back after transportation is done.

Base64-encoded data takes about 33% more space than the original data.

Base64 coding can be used in variety of contexts: transmit and store text that might over wise cause delimiter collision, store passwords hash computed with crypt, evade basic anti-spamming tools (spammers use), encode binary files such as images within scripts, to avoid depending on external files and etc.

This simple online tool is fully compatible with UTF-8 encoding.
