Base64 is particularly prevalent on the World Wide Web [1] where one of its uses is the ability to embed image files or other binary assets inside textual assets such as HTML and CSS files. [2] Base64 is also widely used for sending e-mail attachments, because SMTP – in its original form – was designed to transport 7-bit ASCII characters ...

A binary-to-text encoding is encoding of data in plain text.More precisely, it is an encoding of binary data in a sequence of printable characters.These encodings are necessary for transmission of data when the communication channel does not allow binary data (such as email or NNTP) or is not 8-bit clean.
An optional base64 extension base64, separated from the preceding part by a semicolon. When present, this indicates that the data content of the URI is binary data , encoded in ASCII format using the Base64 scheme for binary-to-text encoding .
HTML editors that support What You See Is What You Get paradigm provide a user interface similar to a word processor for creating HTML documents, as an alternative to manual coding. [1] Achieving true WYSIWYG however is not always possible.
MTOM only optimizes element content that is in the canonical lexical representation of the xs:base64Binary data type. Since there is no standard way to indicate whether data is in the canonical lexical representation, the mechanism for applying MTOM is implementation-dependent.
This means that any binary data one wants to carry in XMP, such as thumbnail images, must be encoded in some XML-friendly format, such as Base64. XMP metadata can describe a document as a whole (the "main" metadata), but can also describe parts of a document, such as pages or included images.
ExifTool is a free and open-source software program for reading, writing, and manipulating image, audio, video, and PDF metadata.As such, ExifTool classes as a tag editor.It is platform independent, available as both a Perl library (Image::ExifTool) and a command-line application.
